An amazing experience when I upgraded my car system, MB Command, with a GTA car kit! It was a very easy install, it took me only about 45 mins from when I removed the first trim parts until I powered up the system.
I have a 2015 - GL550 Mercedes-Benz, and the GTA Car kit is the only one that allows me to switch back and forth between my car system, MB Command, and the GTA Car Kit. Some accessories, e.g. massage seats require to operate them from the original car system. I rate this product 5 stars out of 5! Great product!

Great product.
Very easy to install, and a simple plug and play solution.
Seamlessly works with the factory system and integrated perfectly.
Very happy with the system and believe it is the best solution available.

Great device, and, what is most important, perfect and clear installation guide.

The unit works flawlessly! installation was fairly easy (even for someone who has never taken apart a dash). the youtube instructions were helpful. now that its installed everything is fast, and I'm able to get 24-bit / 44.1kHz (high definition) audio streaming wirelessly through carplay! I'm absolutely loving this!!

Great product. Shipped quick, got it quick. Install is a breeze if you follow the instructions from the video. I did not and had a minor issue and these folks, without making me feel like a complete failure….let me know what I needed to do and BAM. Wife loves it….so winning all the way around! 2016 Porsche 911 Cab.

it’s working flawless in the car. I managed to squeeze the kit underneath the radio unit with bit of a push. The instructional video on the GTA carkit had made it easy to install by myself in my C200.

Thanks

Works flawlessly in the car. It resides side by side with the existing system so it's an added functionality rather than forgoing the OEM system. Had some minor operator/installer issues (my fault) that was helped by GTA customer service to clarify. They stayed on the issue until it was all working great. Appreciate the support.

Installing this unit was one of the easiest installs I ever did. I watched the video several times to get comfortable with all the steps. I recommend following along step by step on your phone pausing, as you perform each step so you have the ability to verify each connection as you make it. One of my concerns was making sure I didn't damage anything along the way and covering the dash with a soft detailing towel helped. All in all it was a very easy install. It is as easy as it looks.

I couldn't be happier with the unit.

The unit works perfectly.

Recently got an '04 TSX. Ordered this kit to compensate for the lack of bluetooth, and it's excellent! Only took about 30 minutes to install. The bluetooth streaming quality is excellent. There's no distortion up at higher volumes. The microphone quality is also great, and I wired the mic right behind the steering wheel instead of up in the A pillar. I am a complete newbie when it comes to DIY car stuff, but following the install video made this super easy. Quick tip if you're having trouble getting the harness cable into the head unit: you can use the magnifier app on your iPhone (or just your front facing camera) to view where the harness cable goes into the head unit. Overall, really happy with my purchase! Thanks GTA car kits!

I am very impressed with the quality of this product. I searched for weeks looking for the best way to add Apple CarPlay to my GLC300 and this was the only product I found that added CarPlay without disrupting any of the car's original functionality. Everything installed and functioned exactly as shown in this video. The whole project took about an hour and I couldn't be more pleased with the result. Thank you GTA Car Kits.....!
