I know this has been posted about before,I have just bought FL yeti in Bronze,upgrading from Roomster. My phone worked fine in the Roomster(Samsung GT S5570). It would not transfer the phone book in the Yeti. I bought a new phone Sony Experia E and within one minute it was doing all that it should,downloading the phone book and looking for call history.Hope this might be of some help to people with this problem. The Sony runs on Jellybean,quite cheap and works fine.

It seems that Samsung have a bit of a track record of not 'toothing well with the VAG BT modules, especially the budget phones.
