I have a full aftermarket system all hooked up and everything sounds great but i have had one problem with 2 diffrent hu's so i know it is something with the car not my head units. I have no memory it is like after 10 or 15 minuets my car goes into a "sleep mode" or something. I can get in like five minuets later and my settings and presets will still be programed but if i wait a while everything resets back to default settings . Is there some sort of adapter i need or something? I've already tried running a constant 12v wire as the power source but still same thing . Oh yea and if this helps any i sat by my car to see what happens after 10 min or so and at about that time margin 10 to 15 min after i turn the key off i can hear a click noise by the fuse box under the hood like something is shutting off. Maybe the car thinks that it is draining my battery or something becuase i belive i have no power after that point like for car phone chargers ect. that should stay on after the car is turned off right? PLEASE ANY HELP ????

i kno exactly what your talking about i did a aftermarket HU in my moms 96 Deville. For some reason it doesnt save the memory, im not sure why. I do know how i solved it though. I simply ran i constant power wire from the positive battery terminal to the yellow wire on the radio and the problem was solved. My moms has a cd changer (fm modulated) and even the constant that it was connected to kept erasing the memory. It may have something to do with the steering controls i guess? IDK but thats the quick fix to your problem and it works just fine.

Yup, very common issue. Try searching this forum you will see lots of discussion about it.

Like ETC97 says, the solution is to hard wire the power to the battery.

They do sell some adapters and such but results appear mixed to bad....so go with the hard wiring technique and tell us what happens!
