    From my windowsill ,inside : it's raining today here
    With 3790 sw i got 5/6 meters ,not so much difference. I really prefere 34xx sw on it, if I could get routes from MS and some more Pois it could be perfect but this probably is impossible.

    You have to navigate to get to the good.

    During the weekend, I've benchmarked 3760 vs 3490 FW for GPS precision during navigation. With open sky and full signal, 3760 has an accuracy ranging between 5-9 meters. In the same conditions and itinerary, 3490 FW accuracy was much worse: 15 - 30 meters. My unit is equipped with PBC V8.
    Such "low" accuracy makes GPS navigation very unreliable. For the moment, I will stay 3460 FW + TurboCCC patch for 3790 features hoping for future development to improve the situation.

    Hi, after downgrading from "3490" to 3760 + 3790 extensions, the system is in a kind of mixed configuration even if I cleared non vol stats after firmware installation.
    Specifically, my unit uses "3490" layout during navigation mode: blue color bar for next destination (instead of green), speed limit red circle (instead of white square). I like a lot this kind of layout and I would like to maintain it in the future.
    Does anybody know where this layout configuration is stored? My idea is to back it up and reinstall in case default 3760 layout appears again in a future FW upgrade.

    Regards,
    Rodrigo
