Today i installed an Alpine CDM 9821 into my car and for some reason the memory doesnt work and i cant figure out why. I followed the wiring code and everything but for some reason. Any ideas?

check to make your yellow wire is to a constant power source and that the red wire is to an ignition controlled source.

Sounds like you tripped your battery wire fuse in the car. Deck will turn on and off but does not retain memory correct..? That should be the first place you look. Then make sure your crimp did not pull out :)
