i installed my deck fine it works good but when ever i turn my car off all my settings go away how do i fix this?

you didn't connect your memory wire (accesory) it should be red on the after-market wiring harness.

i did not get a harness i just cut the wires , what color is the accesory from stock deck or what can i tap into with ez

 

[99prixgt]

What year and trim is your grand prix?

If you cant figure it out just run a wire to the fuse box and hook it to a fuse thats on all the time.

Well just cutting wires is obviously not the way to go unfortuately If you can piece back the wires correctly, I would recommend doing that and getting an aftermarket coupler designed to alleviate just these kind of problems you are having.

Yeah, it's about $10-15 to get an adapter and unless you know exactly what you're doing... it not only makes it easier but (usually) allows for a cleaner install.

Same thing will happen if you reverse the accessory and the power wires.
