Last month for my birthday, my friends got together and ordered me the RSNAV standalone Carplay kit for my 2011 Audi S4.
It came in, and I installed it according to the guide online, and the included manual.
When I connected my phone via USB, it correctly detected carplay and asked if I wanted to enable wireless carplay. If I hold the NAV button for 3 seconds, a click can be heard, and the MMI screen goes black. It never displays anything. If I press NAV again, it switches back to Audi MMI, which works fine.
While in "black"/RSNAV mode, I can use the voice control button to summon Siri and play music, which sounds fine through the Aux input. I just get no video from the RSNAV box.
While in RSNAV mode, if I shift into reverse, it switches to my reverse camera. And when I put it back in drive, it switches back to the black screen.
It seems to me that this must be a faulty RSNAV unit. I got one email back from daniel, who suggested that it was probably the LVDS connector. But, correct me if I'm wrong here, if I get the factory MMI showing correctly, it can't possibly be the LVDS connector - because that means the video signal is making its way from the factory MMI unit, to the RSNAV unit, then being passed through back up to the screen. If there was any broken link in that chain, the screen would be black all the time, NOT just when RSNAV is active. He suggested I try wiggling or putting pressure on the RSNAV LVDS connector while the screen was black. I tried, but obviously it made no difference.
My friend ordered the same product for himself after mine came in, and I installed the unit in his 2016 S4 over the weekend. It works fine, so obviously I know how to install these units.
It's over a week between each email reply I receive. I understand the unforseen issues daniel has had (and has been updating on the website), but is there really NOBODY else capable of addressing support emails and exchanges/returns? There are two other people on Audizine who have posted about the same exact issue as me.
