Since we're hacking things now, NOMAD? 2WIRES? HELP !!

Here's the scenario.

When I had the MK1 system installed in my car, I could drive thru a very rural neighborhood in my car and receive visual and audio navigation instructions using my Navteq 2005.2 disc.

Later, I upgraded my MK1 to the latest version of software for that era hardware, and drove thru the same neighborhood, but received a message across the screen stating "CORRECT DEST. GUIDANCE NOT POSSIBLE" and no more audio instructions were given, but a white line was drawn straight to my destination. Keep in mind, I was using the EXACT SAME 2005.2 Navteq CD.

After dropping the O/S back to the Original version (v.8) the "CORRECT DEST. GUIDANCE NOT POSSIBLE" message went away.

Okay.....so later I upgraded to the MK3 and finally to the MK4, and they BOTH give "CORRECT DEST. GUIDANCE NOT POSSIBLE" when driving thru this neighborhood.

When poking thru the code with a standard hex editor, I discovered a line of text entitled "PARTIALLYDIGITIZEDGUIDANCE=OFF" or something to that effect.

It's my believe that this line of code was DISABLED in later versions of the NAV O/S and hence it keeping the later NAV computer from guiding corretly in EXTREMELY rural areas, but in the MK1, it must have been set to "ON"

Does ANYONE know how to crack the nut of correcting this rather annoying problem ?????
