    Sorry, don't have any more idea haven't seen such a problem before. If you have a different USB cable you can try with it. This is the only thing I can think of. Maybe the problem is coming from the USB cable. Don't know. Wondering what would Garmin support says. Hope you fix it.

    Cheers,

    Something similar as per internal memory formatting case.. but why Nuvi can't be recognized as storage memory - this is very strange. I'm already contacted Garmin UK - let's see what they will recommend..

    P.S. USB cable is Ok - cure firmware loads with success..

    Did you go into Systems in the Control Panel and take a look at the USB ports there?
    You can try to change the drive letter too:
    Click Start.
    Go to Settings and click on Control Panel .
    Click Administrative Tools, then click on Computer Management.
    Click Storage and then Disk Management
    In the Computer Management window, double-click Storage, then Disk Management.
    Click on the Garmin disk drive
    Right-click and select Change Drive Letter and Path.
    Click Edit, select a drive letter from the list (choose a never assigned letter )
    Click OK
    Try also to remove the sd and restart Windows with nuvi plugged in

    Thanks for your suggestions. All that steps were yesterday.. No devices under USB branch, no unknown devices, no disks in Disk management. MAC OS Snow Leopard 10.6.7 don't sees Nuvi too. No ideas

    If after flashing the cure firmware, as you wote the nuvi can display the PC icon when connected with USB cable, most probably it can turn on if you turn it on. It won't freeze. Most probably you can choose only one language (american english) and no voice and no maps also. If that is true try this:

    1. If you start the unit and hold your finger in the lower right corner of the screen it will ask you do you want to delete all user data. Tap Yes. This will clear useless information. Be careful it will delete all your favorites.

    2. After performing that go to the speedometer page and hold the speedo for 10sec. You would enter in a diagnostic mode. Then touch Developer Info -> Non-volatile -> Clear Non-volatile memory. The nuvi will reboot.

    Try this two and then connect nuvi. Also when you connect nuvi with USB cable don't disconnect it immediately. Wait for example 15 minutes. Maybe your computer have show initialization of the memory.

    After flashing with your cure firmware Nuvi stops on "Loading maps", if not connected to PC and switched on. Now i leave it for some time - may be something happens. Btw, my work computer don't recognize it in mass storage mode too.

    Lower right corner doesn't work - i have tried that workaround already.

    @ VMatas

    Now I understand. Well I think this is not good. If after flashing with cure it should not freeze on Loading maps if the problem is coming from problematic files in the memory. But if the problem is in the flash memory this "cure" won't help. This simple trick only helps if the problem is coming from problematic files. Strange if it is still freezing on Loading Maps it shouldn't connect to PC and display PC icon.

    Sometimes older firmwares help. For example you can try 2.50. I have posted such in gpspassion. Just google "Service firmware for 37xx" and you will find it. But I doubt it will help. The problem seems of other type.

    I know there is much more advance ways of repairing memory problems but I know only one person that could do it. But I don't think it's worth contacting with him. Better stop tormenting your unit and contact Garmin Product support.

    2.50 service firmware gives GIR version mismatch error - that was first service firmware which i have tried. I fully agree - such behavior looks very bad :D Garmin already contacted, i'm waiting for response. Damn, what a sensitive unit - with 205 i don't have such problems..

    P.S. With service firmware it freezes on loading maps only when not connected to PC. If i plug it into USB, it normally shows connection icon, but can't be recognized by PC.

    Problem solved without Garmin costly help

    Steps:

    1. Load cure firmware as usual
    2. switch on Nuvi, and tap left top corner, but after 0.5 - 1 secs later, than for pre-boot mode
    3. wait for "Loading maps", then wait 5-7 secs and press power button
    4. wait for copyright sign (C) and release power button
    5. wait for language selector and release top left corner
    6. IMMEDIATELY and very fast tap few times Ok button
    7. Enjoy Nuvi
    8. connect to PC, erase bad files and restart.

    Many thanks to RTuERkaM from gps-forum Russia for its support and persistence.

    P.S. You must experimentally select time in step 3. If selected time will be to short you don't see (C) - Nuvi will be switched Off.
