Minor update… no crazy processor upgrades to my Audi SQ5, but I did add a $300 RSNAV Carplay unit. (No Carplay natively in this car.)
I won’t claim that sound quality is improved (I think it is, tho!), but it sounds great playing Tidal/Qobuz/Radio Paradise via a wired connection from my iPhone. (You can use Bluetooth, but I think wired sounds better, and I have it plugged in and charging by default anyway.)
Also love using my go-to Google maps over the Audi navigation.
Unit’s a little bigger than a deck of cards, and it fits easily behind the head unit/climate controls. All harnesses were included, and there are a few videos out there on installation. Pretty easy.
Biggest pain was having to buy a OBDII device to access Audi’s hidden menu so I could activate the Auxiliary audio input, which is turned off by default.
Other than that, very happy with it.
