2001 Sienna XLE.

recently radio reception has been very poor. it is the JBL 6 disc indash unit. pulled the unit today to check the connection and it is fine, reseated to be sure. then noticed the reception works GREAT when key is in the ACC position, but once cranked lose the signal completely? this is pretty strange. not sure how long its been going on but certainly within the past year. car has been sitting a lot while traveling, but garaged.

any thoughts?

The only things I can think of would be interference from the alternator or perhaps malfunctioning spark plugs. Never heard of this in a vehicle before, but I have noticed that my ride on mower's plugs will interfere with my headphones if one of the plugs needs replacement (I know,

weird...).

Maybe the head unit needs to be replaced on your stereo?

I'm just shooting in the dark here...
Good luck.
