I took delivery of my new Superb Elegance in Aug 2010, and I have never experienced any issues with the bluetooth connectivity with my iPhones until 2 months ago. I originally owned a 3GS and then a 4S from 10 months ago. In November, the intermittent problems started, with the phone not registering as a media player via bluetooth on (apparently) random days, with the phone connectivity itself always working fine. This has become quite annoying, as I regularly listen to audiobooks via my iPhone, and it quite frustrating that I can no longer depend on this working consistently.

When it does not work, I have tried a variety of things with no success: disconnect and then reconnect phone , disconnect and then reconnect media player, remove user and reconnect the phone from new (all with a variety of combinations of: while playing and not playing the audio file, and while car stereo is on / off). None of these things bring the media player functionality back on the days that it is not working. And then the next day it often works, with no obvious reason why. [i rarely use the car twice in one day, and so have not yet observed whether it corrects itself on the same day.]

My wife now has my 3GS, but it is not very practical to test whether this has the same issues (we could swap sim cards I suppose for a few weeks).

Any helpful suggestions as to what could be causing the problem, or is it just a case of live with it and hope it resolves itself over time?

Thanks for your time.

I've had issues like this with my 4S on the odd occasion, it hasn't done it for ages since I reset everything.

The only advice I can give is to start again from scratch:

Delete the Bluetooth pairing from the car via the Bluetooth menus, I'd advise leaving the car overnight so the BT module actually shuts down properly as it remains live for a while after the key is pulled out.

Delete all Bluetooth pairing info on your phone: 'Forget Device' or similar.

Then carry out a cold restart on the iPhone (press and hold the top lock button and the home button at the same time until you see the Apple logo). This forces the iPhone to completely reboot from scratch - no worse than powering it off.

Then re-pair the phone and car and see how it goes.

I did this and the steaming has been fine ever since. There is of course no guarantee that this will cure the problem for you.

A 'Nuclear' option would be to do a full restore on your iPhone which will do a clean install of iOS on the device. Goes without saying that a backup needs to be done beforehand.

I still get the odd problem of call audio not reaching the head unit. In that case I have to reach under my seat and pull the plug to the Bluetooth module to reset it :wonder: but it is rare - once every 4 months or so.

Thanks very much for your very helpful and detailed reply. I shall give this reset a try when it does it again. Failing that, I shall backup and restore my iPhone. I hadn't considered resetting the bluetooth unit itself - that could be my 3rd and final step.

Much obliged,

Andrew.
