Just received my K800i last week and it was able to sync with my RNSE straight away. all functions are available on the BT including both SIm and Phone contacts.
What I have noticed is that the BT pairing will keep dropping and reconnecting if not on a call. No issues when the phone is in use.
THE BT module is the latest version and the RNSE the latest firmware and disk. There are NO updates of firmware avaiulable for the K800i yet.
I know the problem is the phone as it works perfectly with my old Nokia 62310i and my sons K750i.
Problem is I like the phone and dont want to swap.
Done a bit of research and found that there was similar issues with Treo 650's if speed dials were used. Ive deleted mine and thought it had cured it, but apparently not. All the Audi hardware is spot on as it was fitted by Craigyb and ive eliminated that by testing with my old phone.
Interested if anyone has had a similar problem with this phone or if anyone can offer any suggestions to try
