I think that O36 is GTM36
Do You Know What all this means ?
HW V7 Hardware Version of PCB
8Gb Internal User Flash size (Nuvi Drive Size)
O36 ???
DS ???
TC ???
HP ???
GTL ???

Next test results with just 3 files in GPS dir:
City driving - average 15-20 m. accuracy. GPS connected to 11 of 12 visible satellites, not full signal strength /avrg. 40%/. Lowest accuracy 27 m. and highest - 10m.
Strange, but no problem with navigation process, even there I have had 27 m. accuracy. The car icon was always on the right road. All the time full signal strength green bars /not blue one/.
Out of town – avrg. accuracy 13-16 m. Worst – 22m., best 10m.
Time to sat fix – immediately after main screen appearance.
Outside the car to open space with clear view, standing in one place – believe me, I have never seen such a thing – 3 m. accuracy, almost all blue bars on 100%. Beauty!
Conclusions: much better as navigation behavior, but still it is not 3490 or 2595 accuracy and sensitivity. I even start to think that may be my receiver’s antenna was broken and because of that the unit is so case sensitive. I have dropped down unit several times and remembering how fragile were old Nokia phone antennas ….. Unfortunately cannot check, as I am not so good in dismantling.
Here is the file that @isg talking about
[Only registered and activated users can see links. ]
1.) Extract rar from above link
2.) Rename in .System your GPS folder to GPS1
3.) Add GPS folder from step1 on your nuvi in .System folder
4.) Go outside, whait for satellite lock and make procedure for satellite accuracy again
5.) If all go Ok, you will have 3m - 5m accuracy
This is from EU nuvi 37xx --> 34xx with 3m accuracy beside my window i didn't test it on road, but this file test @isg
p.s.
@isg
Thank you for your time and test and for your review

now i test it in nord est of Italy
Some guesses:
O35, O36 - CPU OMAP
GM - GPS chipset MTK
GT (GTL?) - GPS chipset TI
HP - headphones
For me always 8 - 12 meters of accuracy. Any differents from my files. After i copy inside GPS directory, do i must do clear NON VOL or single test for erase all old satellites in elevation secret menu....??
