Okay, so last night I had my Avic F90BT intalled and I was going through the procedures for the video bypass...... . I followed all instructions correctly, and after doing the bypass my unit started consistantly re-booting..... So today I tried changing the value to 256 and that did not fix anything, Finally I deleted the files in the "system" and "save" folders because I read that would correct the re-booting problem. Now my Unit when turing on give the message, "Program application databse cannot be found" , What can I do to fix my Unit. I NEED HELP. Thank you so much.
