I pair my Xperia X with car bluetooth, handsfree call will interrupt the music on the radio as I would expect, so the bluetooth is working just fine.
Now the problem, if I use any navigation app on my phone while the bluetooth is connected to the cars bluetooth, the phone is 100% quiet and no sound from the phone or the phones bluetooth will not interrupt the radio as would expect it to do.
Im a bit disapointed as this is my first android phone and this was no problem in my previous Windows phone.
I have gone through the spec (whitepaper) on the Xperia X, and all bluetooth protocols is the same or better version on the Xperia X then the Lumia, so i cant figure out whats the problem is on this phone.
Any tips or tricks i should know about or is this just not possible on this phone?
