After disconnecting the battery for an install on something else, my d1 senses no cd player and will not angle at all. Tried resetting but nothing. My Installer told me it may be because i left a cd in when i disconnected the battery, but ive done it before without any problem. Has anyone had the same problem or could tell me what to do?

I had this problem but it just stopped being a problem after playing with the option controls...
