my tuner wont turn on tried the remote is there a test i can do thorugh the empeg ?

Is this one of the preassembled tuners or one of the PCA kit tuners? If it's the kit, you may have just wired something wrong. I'm sure someone could help you there. If it's a "normal" one, I'm not much help, either.

Uh, does the LED come on? Does the empeg say "searching for radio module" (or something like that) during boot?

it is a orginal tuner but dont know how to work it it was hooked up my a pro but one blue wire that goes intot he sled came out and he said it would not effect the radio or player think it was the phone wire but can u guys give me a reply on that (blue wire from sled question) thanks

Hmmm, the blue wire is the remote turn on for controlling amps to turn on along with the empeg. It looks like it is also used to power the tuner, according to this documentation of the original MkII(a) sled wiring, which shows a connection between the ISO and tuner plug for this wire.

ok people if u confirm that the blue wire from the sled (amp remote) actually powers the tuner also I will need to recrimp this wire can anyone tell me what i need or how to do it because im not famaliar witht his type of crimping

oh i found those instructions seems pretty easy will take care of it when i get some time but for now i taped down the wire into the connector. I thought there was some crimping involved but per instructions its not. So thanks for your help guys. Im also having alot of interferce when i put my player into the sled. It like a loud buzzing noise that gets louder when I am driving (like when i push on the gas) do you or anyone know how i can reduce or even cancel out this noise

It's called a "ground loop." More info in the FAQ.
