According to the bluetooth helpline of Honda, I need the app "Bluetooth phonebook" to fix a phonebook problem. I downloaded the trialversion from the playstore, which doesn't work because it changes the order of some numbers in every phonenumber. So o.k. I need to buy the app, but it's not in my playstore and if I check it out on the computer, it says: " no eligible devices for app install" or "incompatible with my device". Who can help. Why is it not compatible?
