Lately whenever I end a phone conversation using the button on the steering wheel, it seems like the system has a mini-crash or executes some sort of spontaneous soft reboot.

When this happens the bluetooth connection is intterrupted and the welcome screen pops up.

Has anyone else been experiencing this?

 

there is a tsb out there for a firmware update for bluetooth issues. Take it in to the dealer

 

Yes, my navi crashed twice. First time it was connected with bluetooth something. It happened when I was connecting new phone. During the process car's system freezed and had very slow responses. Some screen's options were missing. I recorded a video of it to have a proof for dealership.

Also I had a problem with Bluetooth module. It disconnected my phone and there were some message "Bluetooth module is missing" or something very similar to that. Sometimes I am experiencing problems with music streaming from phone. It has very small gaps during playback.

They are now updating me whole system including 2015 maps under the warranty. I will let you know if it helped.

 

Excellent, Thanks. I made the appointment with the dealer. I will also let you know if this solved the problem.
