hello guys, i usually post on newcelica.org, seeing that i have a 2000 model toyota celica GT-S (6spd)...i have the PREMIUM sound system on my car, but toyota did not go with the JBL PREMIUM AMP until '03 and up...
okay, so my problem is this. i recently bought a Toyota Navigation Unit, a stock one, for my car. It has the JBL branded on it and everything, and the seller said that i have to have a JBL PREMIUM AMP to run it...E7001 is the model number of the unit
(here is a picture of it in an 04 tundra)

anyways. just because i had a premium AMP already (although not JBL), i decided to "plug and play" it just to see what would happen. i took out my stock radio, and plugged the harness in from the amp to the back of the navi unit. EVERYTHING powered up, and everything works, as in, screens, touch feature, motorized face to slide down to insert the CD's, all that.
Except for ONE problem. I CANNOT CONTROL MY SOUND at all...in fact...it appears as if the volume has been CRANKED up ALL the way. even if i turn off the AUDIO from the unit, my car has this extremely annoying "buzz" to it...even to the point where if i accelerate, the buzz increases. And when i actually turn ON any audio, well, it's totally out of control. The music is blasted to the point where it's unbearable.
My question is, is this because of the fact that i don't have a JBL Premium amp and am just using the older toyota premium amp? or does it have to do with some kind of grounding problem or wiring...? Any help would be appreciated. *note, with normal stock basic toyota cd player, and same premium amp, i have no noise problems, but this cd player also doesn't have the JBL tag on it*
Thanks a lot guys
