I have had my e61 535d since November and my K750i has worked happily until last week. The car went in to have a BMW towbar fitted which requires some reprogramming for the car. Now my phone refuses to pair. The set-up procedure appears to be going fine until I enter the pass-key. The phone gets added to the list on the screen and the phone says its adding BMWxxxx etc. But the phone just stays on that screen until you switch it off and the phone drops of the list again after a minute or so of waiting.


A bit off topic but:

Another little quirk has been my Nav address book shows loads of duplicate entries and neither entry seems to work now, with the Nav getting stuck in the calculation screen till you eject the disk.

One last question, how do I see what firmware version the car is using?

Is it possible you have the cip20 now check with dealer. I have the same phone but with 19.2 I am reluctant to ask for the newer version as there seems to be problems with it. My own experience with this phone and others is to keep trying and I mean keep trying it should eventually work

I tried pairing with my son's phone (W900i) and found that worked. So I downloaded the latest software for the K750i and tried again. Everythign is back to normal now.

Where did you download the latest software Andy? I've got the same K750i, but it works fine for me.

I got it off the Sony Ericsson website from the K750i support page. The bit you need is the updates software. This can check your phone using the USB cable and see whether there are any firmware updates applicable. My phone worked fine too till the towbar was fitted. There is probably not much point in doing the upgrade until you experience a problem because there is always a degree of risk involved in updating.

I've just added my Sony Erricson S700i to my car, wroks great, so stupid I didn't do the pairing the first day I have my car. I might be upgrading my phone to Nokia N90 or 6280, does anyone know if there's going to be compatibility problems? Thanks.
