For Porsche PCM3.0&3.1 System（TAX FREE）

I’m happy with the multimedia upgrade only that when I use aux\mmi interface I get an Echo during my calls

Highly recommend. I could not have asked for a more easier install and for more features at this price range. The only small drawback is some software "issues", and by them I mean the AndroidAuto doesen't always turn on automatically for example. Nothing serious or deal braking, just some final polishing. Please remember to update the software version of this device tho if u buy this, please watch the video on YouTube made by Camden B.

Very easy install. Great Product. Affordable.
Well done team!

Nice! Cant use cars without carplay. Roadtop solved my problem. Thank you

Working great!
