Apparently dead Kenwood head unit can be reset by disconnecting battery?!?

[abillmann]

Hey all,

I've got an old 2002 Acura TL that's been working just fine with a Kenwood DPX792BH head unit until recently. For whatever reason, the unit sometimes goes completely dead sometime after the car is turned off--absolutely no signs of life whatsoever when the car is started again.

When I disconnect the negative battery terminal and re-connect it, the unit comes back to life (with everything reset to factory settings, obviously). It works again for a while, maybe a week or two, then dies again. So I pop the hood, disconnect the battery, re-connect it...and it's fine again.

Any guesses on what could explain this?
