I have a 2011 Liberty Sport with the Mygig RHB radio/sat/gps unit.
Since I've had the Jeep, I've noticed that roughly 5 minutes after starting it up I will hear a soft "tone" or beep that appears to be coming from just the right front speaker. Just a single beep - just once after startup, then not again until I turn the Jeep off and start it up again.
It doesn't matter if I'm moving or not - it still happens.
It actually seems to happen as early as 2 min. after startup to maybe as late as 10 min.
I've turned the Mygig off (just the time on the display) and I still hear it.
This is driving me crazy! I'd just like to solve the year-long mystery already!
No error codes/lights, and nothing indicated on the Mygig.
I'll record and post it if I can.
