Okay... I have VW premium bluetooth (RCD510) installed from new. Up until yesterday it has been working perfectly with my Blackberry Bold 9700 for 2 years.
Got in the car yesterday and phone connected up as usual then 30 seconds later the connection dropped and I get a message telling me that there is no bluetooth connection. Then the process starts again - phone connects but now there is no signal to make a call. 30 seconds later the phone disconnects again with the same message telling me that there is no bluetooth connection. This keeps repeating on and on.
The phone has not been updated in the last 2 months but is running the latest OS/updates. Done all the usual with resetting phone, deleting bluetooth connection and re-pairing with car but the problem still persists

Unfortunately I don't have any other compatible phone to test the car with but my Bold will pair with other phones.
Does this sound like it could be a problem with my phone or has the VW premium bluetooth developed a fault?
Has anyone else experienced something similar?
