pioneer head unit issue?

[deuce106]

hi guys...
i have an 09 camry with a pioneer avic bt90 cd player with build in nav and blu tooth. anyway the unit shuts off and on by itself, but it only happens when i start driving the car.it feels like a loose conector somewhere but i cant find it. if i park the car it works just fine??? i checked the harness and the wiring but they all seem to be ok. i replaced the radio fusses, its still doing the same. could it be any thing related to an alternator or something in that category? please help....
thanks

Either the wiring/connectors/head unit seem to have a problem.

Have the installer look at it.
