I installed a D3 for a customer a while ago. They also have a D1 in another car. The customer inserted the D1 disc into the D3 and now the D3 says disc error even when the correct disc is in. Anyone heard of a boneheaded mistake like this and is there a solution?

Thanks

Probably downloaded the wrong firmware or something and is having an identidy crisis.

Just do the Nav reset by turning the car on and pressing the reset button with a pen.

I appreciate the help. Unfortunately that is not it. The unit won't read DVDs or CDs now either. I think the D1 disk messed up the laser pickup.

Thanks anyway.

A disc isn't going to mess up the laser diode.

If it somehow messed up the firmware, you can go into test mode and force a firmware rewrite with the correct D3 disc. I forget the exact menu option, "Force System Program" sounds about right. I don't know the exact code to get into test mode, but I'm sure it's been posted before.

you should be able to find it on here, i was just exploring the other day and found it but im too lazy to dig it up again.
