Do we have a procedure on how to awitch version 8.351 back to version 8.302 to my GO930 internal memory.I was using 8.302 before I updated to the latest map not realizing when ask to update to latest home which I did but it was too late that I realize everything was change.Now I wnt to go back to 8.302 which I believe is more stable tha 8.351. Thanks in advance.
