Just installed a N3 in my truck and went to load the nav disk in and got a mechanism failed error. The eject button wont spit it out but I can grab it with a pair of needle nose and pull it out.Im new to these and wondering if anyone has any suggestions.There is no paper label on the disk.It grabs it pulls it in but never actually loads it. It pulls out real easy.

Well the unit is clearly defective. You will need to send it off for servicing.
