Hmm, that should do it.. wait, I think i see the problem.

1. Open HexEditor ( xvi32 ) Correct
2. Open files (sw_rel , lng_rel) Correct
3. Edit-->Overwrite strings-->Hex string--->Type "30" (editing v31) wrong

In the first line of each of the hex files you find: 31 30 31 30

Just edit the last 30 to 31 and your nav unit will think it's a new Software Version.

4. Save Correct
