    When toying with tricks which require editing of GarminDevice.xml, I always prefer to copy this file from the Nuvi device to a Garmin root directory on a USB stick. Garmin's updaters will treat a USB stick with a x\Garmin\GarminDevice.xml file as a real Nuvi and will download all required data onto the USB stick. This way the real GPS will be safe from any inadvertent mistakes.

    Does anyone know how to go back to version 2.50 for Nuvi 3790, because the link is not available for download.

    this truly saved me as i seemingly "bricked" my nuvi by trying to upgrade the firmware but bringing it back to the original firmware did the trick. you sir are a lifesaver!

    Anyone knows where I can find Nuvi 265WT any older firmware without the need of Webupdater? Or how can I get my 265WT TW version to flash back to US version?

    2ways for 2x5 Series

    1). put in your gupdate.gcd file within SdCard\Garmin\Gupdate.gcd (You need to delete the previous one first.)
    or
    2). Put in your gupdate.gcd file within Nuvi\Garmin\gupdate.gcd

    Default Garmin gps 2595lmt how to rollback OS to previous version 7.8 please?

    HI,

    I have a Garmin 2595lmt and software is version 7.90. Previous 7.80 there was no trouble with routing mainly via toll roads here around sydney.
    however after the 7.9 update i took a trip and it lead us on a goose chase in Ballarat nearly giving my wife who was driving a 2nd heart attack!
    On our return to Sydney it did not want to use the toll roads even though the avoidances, no toll and no traffic was definitely off. I have toggled these and repowered several times to try and restore good routing operation.

    Can I rollback to earlier software? There has to be a way to do it as further testing has shown there is some ghost in the unit wanting to redirect it away from main roads. I have reset all data in the test (volume, hold topright hand side for 10 seconds menu) and it appeared as a new unit but still it is not calculating the route as 7.8 did.

    come on guys. someone must have a method or opinion on this. I have backups via Garmin Express but there doesnt seem to be an OS backup there. Is there any way i can get a 7.8 image or something an over write the complete device?

    thanks.
