Just wanted to add my symptoms to the thread (in case Apple and/or Honda are paying attention 🙂)
I have a 2012 CRV EXL RES. When I try to use Pandora on my iPhone 4 or 4S connected via USB, I see the following:
(1) Sometimes works flawlessly.
(2) Sometimes I hear nothing but do see album artwork on the CR-V's in-dash display.
(3) Sometimes I hear nothing and the CR-V's in-dash display is stuck on "Loading."
(4) Sometimes I hear very faint audio (kind of like what music sounds like from headphones that you're not wearing) with no bass.
I haven't found anything that will fix items (2-4) above reliably. Cycling power on the iPhone, disconnecting/reconnecting USB, changing audio source on CR-V sometimes help sometimes don't.
When I got my CR-V in late December I had an iPhone 4 (running iOS 5). I since traded it in for an iPhone 4S and have the same problems on it that I had on the iPhone 4. (Although it might work a little more reliably on the iPhone 4S.)
I'm hoping when I take my new baby in for its first dealer service there might be a service bulletin or updates available for the CR-V and/or the iPhone.
Thanks for reading.
