Hi, wondering if anyone is using their XZ Premium with a Sony WX-GT90BT car stereo or any other Sony car stereo.....having quite a few problems even tho it is 'paired' 
It's technically not compatible... or at least, compatibility is unknown.

What issues are you having with it?
@CameronT initially it paired seemlessly, i can receive calls from any number/contacts etc....but when i try to call a mobile number on my list 'ERROR' appears.....if i call a landline number it works perfectly, have checked all settings, tried re-pairing numerous times but no difference.
Yesterday Sony Audio contacted me to reset the stereo which i tried but still the same problem, but now all the contact details ie phone numbers are all mixed up 
Definetly think it is a compatibility issue but interesting to find out if anyone having the same issue.
