    It depend on you are moving or not.
    Stand still + Clear sky I got 3 Meters accuracy.
    On car moving without Signal Radiator I got about 6-8 Meters.

    Thanks aekhong, my values are similar. But at 3790 it was 3 meters while moving, instead of 6-8 meters.

    no matter on the accuracy, it's calculation on the possible position error.

    How about the car "jump" to another road nearby for 16 meter accuracy ?

    I love the low number in accuracy. just my private love. ei ei

    Hi, after a succesful upgrade 3760 -> 3490, I am experiencing a decrease in GPS receiver sensitivity. Specifically:
    -car jumps happens often near turn-points (from 100 meters -> 10 meters)
    -car left behind on complex itinerary (like highway junctions)

    In addition to that, in a 10 kms route, device got in hang state in a complex roundabout and crashed just before displaying a split junction view.

    I'd like to know if such behaviors are somehow expected and should cope with that.

    PS: Speech recognition was activated. I suspect that mic and voice processing may introduce an overhead on normal navigation that causes lags, hang and crashes.

    your info look normal, I trust you made correct 34xx conversion... we faced only we we use original 37xx boot combination with other fw_all and PCB version changed.

    bpb, thanks for your input. Stability has improved after a reset (clear non vol stats) and disabling ASR. Now user interface is smoother and JCVs work fine. However, the big problem is the sensitivy (or lack of it). I experienced jumps > 50 mts today with open sky and full GPS signal.

    Regards,
    Rodrigo

    @ rodrigos

    Many users experience similar issue. (+ crashing/freezing sometimes) Here two question for thinking over:

    - What about the other softwares (regions) of 34xx? Why not also using them for conversion? Main firmware, boot loader and graphical resources (this is what it is included in gcd/rgn) are just part of the 34xx softwares. But not all of them!

    - Are you sure 34xx and 37xx uses the same gps chipset firmwares? (Hint: No they aren't and this software is not stored in main firmware, boot loader and gir which you are using for the conversion)
