bought the avic 700bt 2 years ago .... and it worked fine until early last summer when the software started to act up and sometimes you couldnt see anything on the screen..... found the fx3.1 update and it worked perfect... 3 months later the unit started acting up in the same manner as before however this time it would start with the loading screen then everything would shut down..... can't even get into testmode... i have searched and tried everything on this site for a fix (or i atleast think so)... if anyone has a link or can upload a file for a fresh install i would greatly appreciate it thx.
