I've done several searches, to no avail.
When using MAPS, the audio seems to work OK until going into the NAV mode. Everything seems to work normally when starting the APP or just getting directions. It's only when activating Navigation that the audio goes dead, for everything -- no feedback response from the volume Up-Down, etc. Sometimes, I get the first audible direction command, then nothing more. Audio returns to normal upon exiting the NAV mode. And, yes, I've checked that the Audio is enabled in the App. I haven't used MAPS for awhile, but I don't recall this problem in the past.
I'm running 4.2.2, build JDQ39, and have re-booted and cleared the MAPS cache.
Any ideas? Thanks.
