I have the following iPhone accessories:-
- Phillips DC390/05 Alarm Clock
- Pure Twilight Alarm clock using iDock i-10
- Sony Hifi (CMT-CX5BiP)
I used to have an iPhone 4 32GB on the latest IOS 6.1.2 and it worked perfectly with these devices. I dropped it and smashed it (for the second time) and decided to buy a 2nd hand iPhone 4s 64GB. It arrived and I performed an iPhone restore from iTunes. Everything is great with the new iPhone 4s and it is in perfect working order with no signs of any damage/dirt to the dock connector. But when I try and use it on the Phillips Alarm Clock or the Pure iDock I get the "This Accessory is not supported by iPhone" error and I cannot use them as speaker docks, although it charges fine and work perfectly via the Sony hifi. My iPad, iPhone Touch, iPod classic work fine with all three devices.
When I first got the phone and before I had set it up I charged it on the Philips Alarm clock, I then inserted the SIM card, run the setup wizard to connect to 02 and activate before hooking it up to iTunes and running the restore proceess. After I this had completed the restore, I restarted and then synchronised with iTunes again, I tried to play some music through the speakers but no sound would play, the Airplay option showed only my Apple TV devices and iDock connector as output options. I performed another restart and then it played music happily through the speaker fine. But the problem began with I tried to play music through my Philips alarm clock and got the "This Accessory is not supported by iPhone" error, again the phone happily charged on the dock fine.
- restarting the phone
- Switching off the home screen and connecting to the dock
- Turning the iPhone off and connecting to the dock and turning on
- Reset all settings (Preserving data)
The only thing I can think of is that the Philips and Pure Alarm clocks do extra functionality than just a speaker dock. The Philips synchronises its clock with the iPhone and the Pure dock has an App which allows you to play Internet radio through the dock. Could it be a hardware error or software bug? If its hardware I can send it back as I have a 30 day warranty but rather not go through the hassle if its a software glitch that I can fix.
