And current firmware 2.60 have too many small errors on non CN maps.
Do you mean we all can restore model number back easily after ergn,41 ?
Which way will you advice ?
How about Unit ID after ergn,41 ?
---------------------------------------------------------------
I never deleted rgn 41 after flashed (for many times) with other firmware., just did clear NV by menu.
And current firmware 2.60 have too many small errors on non CN maps.
@voyager56rrgn,41,1:/41_backup.bin
or
rrgn,41,0:/41_backup.bin
Interpreting syntax as:
rrgn, (command to 'read' region)
41, (region location number to be read)
1:/ (sdcard root directory)
or
0:/ (device storage root directory)
41_backup.bin (file name given to dumped data)
@Alexander2010After installing unoriginal firmware good way to clear NV is
ergn,41
But you lose your model number (not big problem).....
I followed tutorial advice about accessing NVM menu to clear NVM. No ill effect on model number, so IF achieving same outcome it would seem to be safer method?
Leads to question: Is it possible to recover original (or change) model number by rewriting original rgn 41?
@Alexander2010And NEVER erase regions 05 and 43 - it kill your device.
That is GOOD to know!! Thanks
@lolypop000
These two were missing from update.txt file you pm'ed me. I have added them.
rrgn,48,1:/reg_48.bin
rrgn,148,1:/reg_148.bin
To lost model number on 3490 firmware maybe no much effect to functions.
But it is different if you lost on 3790 firmware.
I got 37xx with less functions. (No 3D Building ability)
I flashed to 3490 and got 34xx but I had 3D Building.
It means to lost model number on other nuvi series may not be a happiness.
Except we test and find no side effects on every nuvi series so ergn,41 is a must thing to do.
Model number - this is only appearance. All functions can be enabled via xml to 37xx. In the earlier models (1xxx, 2x5) model number does not affect the function.
