installed my hu myslef...question...

[Ugly Pete]

everything works fine, i had an aftermarket one in there already, but now the memory doesnt get saved in. (bass trebble station settings) i checked the yellow wire and its connected. anyone know what could be the problem?

your HU is not connected to a constant 12V source. The wire that is blue with the yellow stripe is constant 12V.

[Pribilof]

you can always get a voltmeter and test for a constant source. But that's most likely your problem

[Ugly Pete]

hmmm. i thought yellow was constant. thats the way it was in my nissan :P thanks guys.

Resurrecting this thread just for clarification.

Installed a headunit last night. Turns on but settings do not get saved. I just have a little confusion to what color wires the HU red & yellow wires onto the stock wiring.

Thanks!

THANKS!

And just checking: no more than 2 amps/crossovers/etc connected to a single remote? I read that somewhere in this search.

Problem: did the yellow/blue - red & yellow - gray connections. Settings still arent being saved. Radio turns on & off though like it should.

EDIT: Blue/yellow is memory; gray is 12v.

Yes,Blu/Yell is constant 12V
Gray is ign switched 12V...
Check your fusing.

Yeah, everythings working now. It's just that yellow goes to blue/yellow & red goes to gray. And, yes, I did discover somewhere along the way that the radio fuse in the passenger side box was out & needed replacing.

I should have just looked at larryd's wiring FAQ.

Thanks again.

Bassakwards damn radio.... red is usually battery... yellow is usually switched... so much for standards....
