IrelandYeti

Hi, I have a 2012 Yeti Urban (no idea what Bluetooth version it is) with the Belaro system (not sure if that makes any difference) but having some MAJOR issues with the bluetooth. My partner has a Sony Xperia from @2 years ago and I had a HTC Sensation XL that both worked perfectly with both my previous Yeti (2011 Yeti Ambition) and my current Yeti. However, I changed my phone to the Xperia Z and having no end of issues. It connects alright and creates a new profile for the phone, then takes an age before it tells me "Connection Not Possible" to the meda player (which is fine - don't use it) So the phone and bluetooth play along happily until I restart the phone. Then both the phone and the Yeti decide they don't know each other at all, and I have to re-pair them both and it creates a new profile. Obviously after 2 days, I need to delete all the profiles (even though they are all called "Xperia Z" which confuses the Yeti altogether and freezes the whole system if I try to delete them, so have to rename them, then delete them. Then the whole thing starts all over again. Since all this started, I've noticed the radio has come on a few times without the touch-screen activiated, just left with a blank screen, have to switch the radio off and on again to get the "Welcome on Board" message. Not sure if I've messed up the whole system on the Yeti with this new phone! Have tried a factory rest on the menu in the Yeti as well, no luck :-( Any ideas?
