I'm looking for other Kenwood D710A owners who have had this problem....

I installed a new unit in my car a month ago and in my second week, I had the following happen twice:

The radio was set up to run APRS beacon on channel A (using Green Light GPS-710) and scanning VHF/UHF memories on side B.

I would hear a pop in the speaker, side B would stop scanning and after about 3-4 seconds, the unit would shut down.  While scanning was stopped, the decimal point continued to flash like it does when scanning has stopped on an active channel.  Since it pauses for 3-4 seconds, it sure doesn't seem like an intermittent power connection.

I ran the unit for two weeks not using APRS with no issues.  While this isn't proof, I suspect the radio received some bad data and doesn't handle the exception well and shuts down.

Anyone else seen this?

Other data:
R/T software is up to date.  I see I'm one version behind in control head (2.10).

R/T is mounted on structure between the rear speakers in the trunk.  Temps have been relatively cool this fall.

Always run on low power setting.

Power wires run from battery to R/T.  Only mechanical connections are at the battery, Kenwood supplied power cable connector and the fuse holder.  10ga.
