battery problem?

everytime i turn my car off then back on again nothing will save like the time resets deck resets but if i turn it off then start it up again right away it usually saves can sum1 help me haha thanks

The time on the deck or on the dash? I know that when I got a deck installed at future shop in another car the deck was the same way, lots all memory when turned off except if i turned it back on right away, and I brought it to them and they fixed it, it was just wired incorrectly.

ya man if its just the deck then your memory wire wasn’t hooked up properly

nope the time on the dash resets everytime too… and the deck… and the battery light is on but very dim
