I enjoy listening to lossless audio whenever I can, so I opted for a wired Android Auto connection for that reason, and also because the wireless charging couldn't keep up with the battery drain from the AA, and also because I like to use the car's WIFI connection which I found out you can't do while using AA wirelessly...
Am I one of the few who prefers the wired AA connection?

 

wireless charging is always going to suck compared to wired but have you looked into a faster cig port charger?

 

I actually just started using the USB data port... to my ears the music sounds better, and my phone charges faster...

 

I prefer wired, but have had more issues with connection issues than I have with my wireless adapter, which has left me dumbfounded. I've tried every sort of cable from the low end no name brand to OEM cables and for whatever reason, the connection just doesn't seem to be as stable as wireless. I just use wireless now as I find it more convenient. The base system does a good job still of playing music and I haven't noticed a difference in quality wired vs wireless.

I think you may be the only one.
