ok I just got my first system installed (yes i am a complete noob lol). the head unit that i have is an alpine cda-117. When i first got it from the shop (installed) they had it customized and completely preset. A few hours later, i was messing around with the controls just checkin things out, and now everytime i start my car, the unit doesnt turn on until i push the main scrolling button. Also, it always goes to the radio and never saves anything that i set it to. For example, I will set my subs on level 12 and then turn my car off, then turn my car back on 5 minutes later and my subs will be turned completely off. I have read the manuel and it is a little confusing to me. Any help would be greatly appreciated!! Thank you in advance!
