For Porsche PCM3.0&3.1 System

Instructions for the GS series need a bit of additional detail since 2012-2015 have a permanently split 12" screen display where navigation always can't fill the whole screen and other info is displayed on the right side, while 2016-2019 models have the navigation screen fill the 12" screen. As a result, instructions should be updated to reflect the model years 2012-2015 which must select 7" or 8" screen size in dip switch settings, vs the 2016-2019 which can select the 12.3" size dip switch settings. With current instructions since my model is 2013 and i selected the 12.3" settings as suggested in the instructions, the carplay interface is cut-off by the OEM right-side display. Other than that the installation is relatively simple if you have the right tools and watch other folks disassembly procedures on Youtube for the head unit and display. Everything works as expected, except the joystick control is all over the place in the Carplay window area, clearly not easy/designed to work with the OEM joystick. However with some care it does work, and it's best to use Google Assistant for voice control in getting directions, or playing music etc - rather than enter them. The vendor should post the FW updates for the boxes in the portal, currently you can only get them by contacting in whatsup

Overall the functionality of the product is great. This would be a 5 star review but the unit I received didn’t contain the latest instructions and I spent 3-4 hours extra troubleshooting to no avail. Additionally, It took some time to determine how to contact the company (Use the chat feature on their main website which was responded to within ~6-8 hours during their work hours in Asia). The company provided me a link to an updated install manual which had additional Dip settings for my Bosch head unit not in the manual that came in the box. This should have been available on their website or they should have provided an insert with the latest changes. Easy fixes and would have prevented any reason to need a support request.

Works great, just wish it would have better control with the joystick. Overall I’m really enjoying it!!!

Over the last few years I have tried many brands of Android Auto devices and settled on the ordinal Road Top 8.8. Recently I had problem with that unit shutting down due to heat issues, this caused me to re investigate the newer generation products. Once again, the Road Top 8.9 has come out on top. Everything works, wireless android auto, steering wheel controls for both music playback and phone, phone call audio is fantastic and the screen is fantastic.

Works perfect as discribed
