thks for the quick reply.

just so i understand you correctly, BB & CC both carry the audiovox 'near replica' version including the in-dash housing? (i prefer not to ebay)

as far as i know, either system taps into the 12V battery and wouldn't interfere with the hybrid components, but you're right - should an unrelated electrical problem happen, the stealership might try to deny the factory w'tee. last time i was there those bastards were telling me i should be changing my fuel filter every 15K. they said it with a straight face, as if i just fell off a turnip truck or something.
