I'd love to know the source of this information 'cause I'm pretty sure he/she is wrong and you're going to end up with a non-functioning Nav unit.

A Clarion employee used to frequent the Audio Forum and he was pretty adamant that you cannot simply cut wire(s) to bypass the safety feature.

Then again, I've been wrong before and if you're right you could save a lot of people a lot of money (vs. buying the lockpick).
