Hi

I have the newest firmware (R1BC002) on my Sony Ericsson K750i and the correct snap in adapter for thi phone. The X5 is built on januar 2006 and therefor quite new too.
Not all adresses from the phone where syncronized and the voice won't be work on the nav system (SA 633).
On the sony ericsson forums it's described to downgrade the firmware (f.e. to R1AA008). On the other hand it should be possible to upgrade relavant bmw firmware. The nav firmware itself is also up to date. A brother of me with the same nav system gave me a cdrom a few day before with the newest firmware (out of this navigation forum)
Is there any experience what to do or should i contact my bwm support in germany?

Thanks.

Axel
