hello 12 volt gurus: i installed a blaupunkt sacramento on my 2000 camry, to replace the stolen factory unit. but when i power the unit up, and turn up the volume i have to turn the knob till it hits 30 on the volume meter in order to here any music, i tried all of the adjustment but to no avail, is this normal on this head unit..

Not normal for any head unit. Was there a factory amp in the car? Did you use the factory speakers and wiring? ------------- Support the12volt.com

Dyohn. yes i used the factory speakers, and i dont know if there was an amp, i used the crutchfield kit that came with the radio and followed the instruction.

I don't know if your car has an amp either, but come to think of it I believe the Blau has a mute button just above the volume control... make sure it is not on... ------------- Support the12volt.com

Dyohn: hello, yes the head unit has a mute button but its not engaged. the problem is i have to turn the volume knob 1/2 a turn before i get any sound. thats why i think theres something wrong.

the Sacramento should have loads of get up and go... i would suspect a pinch or short on a speaker wire or as DYohn suggested you are going through a factory amp possibly... the Camry does have an amp under the passenger seat... did you use the amp integration harness or did you use the deck to speakers harness and bypass the amp? if you look slightly to the right of the radio you'll see that the wiring from the amp comes back up to the radio and couples to a shorting connector... this way the vehicle is wired for both an amp or for the non-amplified radio only option... i usually unplug this set of plugs and plug directly into the connector with a Metra 70-1761.... is this the plug you used or did you use the 70-8112? ( doubtful since the Sacramento doesnt have dual pre-outs) ------------- Kevin Gerry

Sounds like there is a crossed or shorted out wire or you have a bad head unit. I don't know much about the blau line of car radios but make sure your unit is grounded real good and the antenna is connected. Some units use the antenna as a ground. Another thing you can try is to disconnect the entire unit and rewire the harnest wire by wire as you test it. Wire the 12+, acc, ground, amp on if needed. Than wire up one speaker and test the unit. If it plays louder just go speaker by speaker.

kgerry: the head unit has alot of power, it sounds really good and loud, no problems there. all the wiring is per diagram from crutchfield and i solder all the wiring and used shrink wrap. dont want to brag but i did a good job, what i am trying to say is that when i power up the unit and i turn the volume knob, the unit displays the amount of volume 1-100, but i get no sound until it reaches like 20 on the volume display, you know from 1-20 seams like i dont get any sound. i talked to a professional installer today and he said that it is normal for the blaupunkt radios to do that, i just dont know whether to believe him or not because i still have time to return the head unit back to crutchfield...
