GoGroove FlexSmart x2 Review

I was just in your spot. You want to listen to your playlist from your phone on your radio. But to get that AUX Cord or Bluetooth upgrade it may cost you up to $300, and the installation is just a headache at that point. Luckily for you, here is the GoGroove Flexsmart X2 Review.

The $30 tool that plugs into your car aux outlet right next to your radio, and lets you play any music from your phone with no complicated wiring or anything. Literally plug and play! It is hands down the best car Bluetooth FM transmitter for this price-point.

How Does It Work? And Setup, GoGroove Flexsmart X2 Review

Well, it wouldn’t be a good GoGroove Flexsmart x2 review without actually explaining how easy this thing is to use!

All you have to do is this:

That’s right. No wiring, no complicated apps, no weird instruction manuals, no car kit. In fact, I got mine setup in less than two minutes. I was so amazed by it, it prompted me to write this GoGroove Flexsmart X2 Review.

I was looking for cheap radios to install, but the videos and wiring looked so complicated and dangerous. What would happen if I shorted out the car’s computer? That’s a $400-600 repair alone!

Luckily, this is an easy setup.

Quality/Does it Sound Good? – GoGroove Flexsmart X2 Review

Honestly, I was incredibly surprised by the quality.

I personally drive a 2006 Mustang, with the Shaker 500 radio. So, the radio isn’t good. In fact, many ford enthusiasts complain about how bad the radio is all over the internet.

So for this GoGroove Flexsmart X2 review, I tested the FM transmitter on multiple cars with different speaker systems.

The quality is incredible! Basically crisp and clear. It’s just like any other radio station. There’s no noticeable static or any weird noises like that.

It’s super loud, good bass + treble, everything acts just like it’s a normal radio station.

I’ve had problems before where the FM transmitter had super bad music quality. The quality here is crisp and clear. It works great!

The GoGroove Flexsmart X2 Review wouldn’t be complete with a quick rundown of all the controls this neat gadget has.

The thing is set up like a rectangle. On the left-hand side, you have a circle.

The circle has a dial in the center of it, and three buttons surrounding that dial.

When you turn the dial, it will change the FM frequencies you are transmitting to. It displays that frequency on the LED screen on the right.

The three buttons are: Next, Back, and Pause.

These buttons are SUPER helpful. You can easily just click pause if you need to stop the music. This stops you from having to grab your phone, fumble it, try to find the small pause button, and get into a car accident at the same time.

The same thing goes for the next/back buttons. You can just skip songs easily while keeping your eyes on the road.

The Phone Call/Connect Buttons

On the right-hand side of the rectangle, there are two buttons. One is on the top, one is on the bottom.

The top one is the answer call button. You can press it to answer calls, or hold it to redial.

The bottom button is the end call feature. It ends the call, or declines an incoming call.

Can It Take Phone Calls?

Sure it can! This is especially important in this day and age where you are required to make hands free calls or face a citation.

I know for some audiophiles this phone call part may not be important in this GoGroove Flexsmart X2 Review, but it is crucial. Many people have businesses or need to take urgent phone calls.

If you’re streaming music and a call comes, the music will just stop. You can choose to answer/decline the call.

From there, you just speak loudly towards the FM transmitter. It has a microphone on the side of it. Then the call is played to you through the radio.

I personally have it disabled as I don’t like calling in general when driving. But, sometimes there are emergencies and you need to call.

Does It Have USB Ports? Aux ports?

Yes! I actually would not be writing this GoGroove Flexsmart X2 Review if it did not have USB Ports.

I use the cheap, high-quality 1080p, and super reliable VIOFO A119 V2 dashcam when I drive. I’ve had it for a year now and it’s never failed me.

But, the VIOFO A119 V2 uses a USB port to be powered on. So, if the FM transmitter didn’t have a USB port I wouldn’t have bought it.

My mustang only has one auxiliary power location, so I can’t just move the wiring further.

The GoGroove Flexsmart X2 has one USB charging port under it. This is something I think they could have improved on.

I think we could’ve gotten two USB charging ports. However, at that rate, it may not be holding enough charge through the device, so I get why it might be limited.

Also, it’s worth noting that the USB port does not let you play music through it.

This makes it hard if you only have one AUX power slot and need to have something like your dashcam plugged in there.

This is bad because you may not be able to charge your phone or anything when you drive.

So check out your car if this is a problem for you. If you’re driving a premium car, or like a big SUV you probably won’t have to deal with this. But it is definitely something to keep a note of.

Multi-Point Pairing – My FAVORITE Thing!

Something frustrating with a lot of Bluetooth devices is that only one person can connect at a time.

Luckily, you and your friend can both connect to the GoGroove Flexsmart X2 at the same time!

My girlfriend and I have it set up to do this, so whenever we get in the car, we can both have our songs playing when we want to.

So for example, my song (which is way better than whatever she’s playing) is coming to an end so she wants to play her Mac Miller. So then she just hits play on her phone and it plays her song.

It doesn’t require her to kick me off of the device or do any complicated disconnecting. It just lets both of us play the song we want to play on either phone at whatever time.

Is your best friend playing something that is making you question your friendship? Just hit play on your phone, and he will get the hint without either of you having to awkwardly disconnect his phone.

Is your girlfriend playing something that’s going to lead to divorce in a few months? Just switch the song on your phone and save the marriage without the hassle of awkwardly turning her Bluetooth off in front of her.

This GoGroove Flexsmart X2 review is important to read. I think the FM transmitter is way better than any other transmitter for this reason alone.

Being able to have multiple people share the radio in your car not only gets you to hear different music but lets everyone have fun in the car. Plus, it builds better friendships. (And shows you which friends aren’t worth it. –If they’re playing Juice WRLD- keep them.)

Will It Drain My Car Battery? – GoGroove Flexsmart X2 Review

This was a question I had myself. My car has well documented electrical problems.

The alternator doesn’t fully charge the battery usually and the battery and alternator go out all the time.

So, not draining the last 5% of it is always nice.

To answer your question: No. The GoGroove Flexsmart X2 will not drain your battery. For starters, it has a power button. This lets you easily turn it off when you’re leaving the car.

Secondly, the power draw is nowhere near enough to ever drain your battery unless you’re not driving for weeks.

Take it from me, a Minnesotan who regularly drives his car in -16 degrees Fahrenheit weather. As if my car battery couldn’t take enough.

GoGroove Flexsmart X2 Manual

My packaging of the GoGroove Flexsmart X2 didn’t have a manual. Luckily, I have found one online. You can view it here: GoGroove Flexsmart X2 Online PDF.

The manual is very informative and easy to read. Plus it has great instructions to help you with any problem your FM transmitter may encounter.

GoGroove Flexsmart X2 Review – FM Transmitter Volume Too Low!

This is a common problem for many people, but has a fix that will take seconds!

FM Transmitter Volume Too Low

Fly Bee created an excellent video demonstrating how to fix the FM Transmitter volume too low problem. Many people complain about this, so it has to be included with the GoGroove Flexsmart X2 review.

Honestly, it’s kind of confusing to find the volume button.

Furthermore, sometimes right out of the box the volume will be at 02 or 03. So if you get it to work, it will sound like the GoGroove Flexsmart X2 is just whispering to you.

So all you have to do is turn the knob in the center up. Just like a dial for your oven or radio volume. Then it will display a number from 00-30 telling you the volume it is streamed at.

The GoGroove Flexsmart X2 is a Car MP3 Transmitter – AUX Cord

The GoGroove Flexsmart X2 isn’t just for transmitting via Bluetooth. It can transmit from an MP3 player via the aux cord!

This makes the GoGroove an incredible option to buy.

All you do is connect your MP3 player to the GoGroove Flexsmart X2 via an aux cord.

The FM transmitter has a little 3.5mm aux jack on the top of it that you can plug directly into.

After you plug it in, it will stream that to whatever FM frequency you desire to your radio.

This lets you have an aux and/or Bluetooth connection on older cars that don’t have these features!

How To Fix FM Transmitter Static Problem

If you’re looking to fix FM transmitter static problems with the GoGroove FLexsmart X2 look no further!

I have personally had many problems dealing with static problems. And looking online didn’t really offer much help.

So here are my guidelines for fixing static problems. This really is the best GoGroove Flexsmart X2 Review you’ve ever read. 🙂

  • Make sure you’re on an FM frequency that isn’t used or empty.
    • There are many websites that share empty FM frequencies based on your area. This may change county to county so be careful to make sure you are actually on an unused frequency.
    • The GoGroove Flexsmart X2 Mini has a built-in empty FM frequency finder, but not the normal X2 doesn’t.
  • Try turning off your radio and turning it back on. Sometimes these older radios have a weird time processing multiple frequencies, especially when some are stronger/weaker than the others.
    • This is kind of like restarting your PC. Usually, most radios can turn on/off in 1-2 seconds and fix the static problem.
  • Try chopping off the antennae on your car. A Redditor /u/SupermanV2 suggested doing this and said it worked incredibly well. They stated if the antenna was cut, there’s less competition from other radio networks.
    • You can also just disassemble the antenna, that way if it doesn’t work you can reattach it with just two screws.
  • Try switching to a different frequency. Sometimes I just switch between two frequencies and it fixes static problems instantly. I figure some people may be broadcasting illegally on some of these unused frequencies for illegal activities. And you know what, I have no business in disrupting that, I will just change the frequency periodically and leave them be.

Those are the best ways to fix any static problems with this.

Unfortunately, there’s always going to be a very tiny amount of static, this is just standard for any radio using an FM/AM frequency.

Even if you’re tuning to a big radio station in your area, there is always a small amount of static.

How To Boost FM Transmitter Signal

There are many people out there that may have complaints about the GoGroove Flexsmart X2 review range.

While in this GoGroove Flexsmart X2 review I fully think the range is more than enough, some want to know how to boost FM transmitter signal from this device.

The design of the transmitter is pretty simple.

This video by JimPlicit should help point you in the right direction:

How To Boost FM Transmitter Singal on the GoGroove Flexsmart X2

While he doesn’t tell you how to do it for this model of the transmitter, the idea is still the same.

Take apart the transmitter, and do what he does in the video to the antenna section of the Flexsmart.

This will get you increased range, and hopefully better music.

GoGroove Flexsmart X2 Stopped Working

While the GoGroove Flexsmart X2 Review vouches that this is a great product, stuff happens and sometimes things break.

If your GoGroove Flexsmart X2 stopped working, here are a few things you can try to fix it.

  • Is the On/Off button working?
    • Amazon user B.Harris states that his On/off button wiring broke in half. He listed a method to fix it here on Amazon. He said just a little wiring and some mechanical work got it running again. Then it broke again a few months later. But, if you need a fix for the next few months while they ship you a replacement, it’s worth it.
  • Not a functional unit.
    • Sometimes the company screws up and gives a defective unit. Just contact their warranty and they will get it fixed up.

There aren’t any really known “defects” with these transmitters. There’s nothing that commonly breaks on them, or is known to break.

If something breaks, it’s usually just a random chance.

Conclusion of the GoGroove Flexsmart X2 Review

Overall for this GoGroove Flexsmart X2 review, I’m going to have to say this is a great product.

I’ve tried it on many different cars, it has held up incredibly well, is super easy to set up, and more.

It allowed me to stream music to a radio that didn’t have Bluetooth or an aux cord and play the music I like.

And at less than $30, the choice is clear. Purchase the GoGroove Flexsmart X2 now, and start jamming the music you want.

Tell me in the comments if you’ve used this FM transmitter, and what you recommend.
