I thought about this but I guess my test was half way… I did cut off the Bluetooth on my phone while Navigation was acting up and it continued to act up with the phone disconnected… I thought that ruled the phone out but I will dig deeper into this; It could be related with the V1 cellphone app… After few cellphone OS updates (I assume some app updates as well) the app warnings are now coming through the audio system instead of cellphone speakers. Thanks for the pointer!
