Great upgrade, installed into my 2015 GL550 with no issues; I still have access to AM/FM/SiriusXM Radio and bluetooth through the default Mercedes COMAND interface if I need it.

Not complicated but does take some confidence to do. Overall took me a little over an hour including the 15 minute waiting period to make sure the new Engineering Mode settings took effect (it’s for enabling AUX input, directions are mentioned in the setup instructions).

At one point while adjusting the settings in the Engineering Mode menu, I ran into something I had a question about so I emailed GTA car kits about it. They got back to me in exactly 15 minutes which I really appreciated since I emailed them past 5 PM ET.

It’s pretty much exactly what I was looking for, a drop-in unit to add Android Auto to my car. Works with all the built-in cameras for my car (which has front, side, and rear cameras).

I will say that the voice call quality (coming from whoever you’re calling) isn’t as good as what the stock Mercedes COMAND offers, but that’s not a big deal for me. Might just require some fine-tuning in the audio settings.

Another thing to keep in mind is that as you hook up all the cable harnesses, make sure to do it in a way that doesn’t result in any weird kinks and twists so that re-installing the head unit is as pain-free as possible.

Simple to install. I love the fact this is all self contained inside the radio head unit, without the need for additional hardware, like some other kits. Installation took us about an hour, and all was straight forward. We had one question during off hours and received a response within the hour. Many thanks.

I got a 2006 Toyota Corolla with almost 380k miles for free recently, an incredible gift, but I realized that the factory stereo it came with didn’t have bluetooth or an aux port. Music is a big part of my life as a music teacher in training, so I despaired being limited to just whatever was on the radio or discs I could find. I came up with the interim solution of buying blank discs, buying albums on my laptop, and burning the albums on the discs to play in my car, but that became a little expensive over time, and I was limited to just the small selection of albums I bought. I considered trying to get cheaper CDs online and searched my house for old CDs I had growing up, when I stumbled across a reddit thread that mentioned this site. I was skeptical at first that there could actually be this easy of a fix, but when I read the reviews, watched the videos, and GTA Car Kits very helpfully answered my questions via email, I thought I would give it a go. I ordered the aux kit and bought a couple things necessary to install the kit, and tried installing it today. It worked!! I plugged in my phone (aux cable to lightning adapter to stupid aux-less iPhone), pressed the disc button a couple times, remembered to turn up the volume, and voila! Full stereo sound coming from my car’s speakers! I had almost given up hope that there was a cheap option to get my music playing in my car, but this kit and GTA Car Kits really came through. Thank you!!

Installed in a 2014 Carrera S- I really can’t say enough about the great customer service with email communication from Vitaliy and Maurizio! I had issues with missing sound but they referred me to another video where the optic audio cables were removed from original harness to the new harness. Unfortunately I broke a piece of plastic from one of the ribbon cable retaining clips, and was panicked that the part was nowhere to be found despite googling so many sites. GTA guys provided me with a replacement clip for free! Now everything works as it should and could not be happier with the upgrade!

The video is great to get all the connections done and how to get the trim and stereo out – the one thing I would add though – is if you are struggling to fit the unit behind the stereo like I was – and I mean struggling – KEEP READING.

I tucked the cables underneath the lip you will find right below the stereo – seems like a good place for cables etc to go – but the stereo was facing interference with the module when it was placed behind the stereo unit as instructed in the video. So I reached out for help to GTA and they suggested behind/beside the glove box is also doable. I took a quick peek opening the glove box and it was 4 torx screws you can EASILY see to pull the glove box out (undo the dome light in the glove box – easy). Took 2 minutes to get the glove box out.

Then right there on the left of the glove box is a perfect place for the module. There was a clear pass through (not hard to fish wires at all) to behind the stereo so i just ran the cables from the stereo that were going to the module through wide open pass through – connected the module – and then tucked the module just to the left of where the glove box was going to be reinserted. After struggling for a few hours to make it fit behind the stereo – it took me 10 minutes with this solution.

DO NOT BE AFRAID to remove the glove box and tuck the unit there -it is WAY less work than you think. Wireless carplay works perfectly – i tucked the antenna under the vents that you remove first as the video suggested. I did run the female USB connection as they instructed in case I want to plug directly in but so far no issues with the wireless connection at all. Instructions were all clear – just hope someone reads this when they can’t fit the module right behind the stereo. It MIGHT be because my stereo was a the disc changer version and their video shows a single CD player version – although they do look to be identical in terms of size – maybe there is an extra cm or something on the back that causes an issue. Thanks GTA – the support after purchase was excellent and I really appreciate you guys!

Just installed this unit in my S-Class Coupe. The installation video covers every detail, just might have to watch it a few times 😉 If you’re installing for yourself and not a professional, take care not to drain your auxiliary battery from leaving the interior lights on, etc. while you’re working on the vehicle. Had to replace mine….

The unit works as advertised, seamlessly switches to camera when backing up, calls sound good, all the buttons do what you expect. Very satisfied!

Installed this kit on my Mercedes C300 2016 through the video tutorial (I recommend carefully watching it through) and it went smoothly. I did run into the problem of bypassing the fiber optic cable but Vitaliy was very patient and guided me through a solution and the kit works 100%. This kit took about 1-2 hours of labor. Once set up, it offers seamless wireless connectivity for both Apple and Android devices, allowing for hands-free navigation, music, and calls, and provides a nice modern touch to older infotainment systems. The interface is responsive and integrates well with the existing display. The build quality is solid, maintaining the vehicle’s factory look. While the kit is a bit of an investment, it’s a cost-effective way to upgrade your vehicle’s tech without buying a new car. Overall, it’s a practical and valuable upgrade for enhancing your driving experience. I would highly recommend!

110% recommended. Simple plug and play install. A video that actually shows how it actually works and installs. AMAZING customer support and backend support. I would recommend this for anyone

I have a 2010 997.2 with the Bose option and XM. I have found the installation of this product to be straightforward, I have been able to use Apple Car Play without any issues since the installation. I’m very happy with this product so far.

My Quarter 1 2018 GLC350 sat nav does not show the current speed limits. So I bought the GTAcarkit. This gives me CarPlay and the option to use Waze that mostly shows the speed limits. This is essential in the highly enforced police traffic monitoring in Australia. Vitaliy helped out with initial sound issues by advising iphone setting changes. I am very happy with the upgrade
