Sorry if this is too old to bump, but haven't found any similar threads.
I have an AVIC BT 900 and use it with an iPhone 4 (just use this for music, sits plugged in all the time).
All worked fine until a few weeks ago and then I started getting the "iPod connection failed. Please reconnect" message everytime I started up.
Tried the reset method as described and it initially worked when I tried it last night, but this morning I got the message again.
Nothing has changed - the iPhone firmware was upated to iOS 9 a while back, but worked fine subsequently.
Anyone else with any
