Updating via bluetooth has to be the most antiquated nightmarish PITA way of having to do this tweak. A dat file for USB, a file burned to a cd, anything but using a system that is open to so many variables like Bluetooth. It took me multiple attempts via different Bluetooth options including 2 pcs with heir own Bluetooth and a Bluetooth dongle. For me it worked eventually, but looked like it was in he process of failing when it finally hooked in and finished despite saying transfer failed.
It's a minor complaint about the way he firmware has to be updated rather than the actual firmware.
I am just glad to have steering wheel controls back.
Ooh, before I forget. Apple broke it. It worked before he ios6 requirement. So regardless of where the glitch in backwards compatablity was, apples update exposed it and yes, it broke it for many users. So apple broke it. It may have been inherently defective (but working) on iOS 5, but apples update created the problem people are suffering here. So the apple fan boys and those intent on saying the blame is related to 3rd part coding, take heed, it worked fine UNTIL iOS 6. ergo iOS 6 made things stop working, which leads to the obvious statement that apple broke it.
If we really must put up with harping on, can we just say that the issue COULD have been rectified by apple letting users choose from Bluetooth versions rather than forcing the new version on users? Not rocket science. Instead we were faced with a wall of silence from apple. Some users could perhaps have gone back to ios 5x if they were quick enough. Others like me who bought an iPhone 5 were stuck with waiting for pioneer to sort it out.
I lost a lot of respect for apple over this whole issue. I doubt I am alone in that viewpoint.
