    Thanks Neil!

    I found v3.60 on my one backup but struggling to get it to see my maps =(
    If I use the unmodified map its says maps are locked then I unlock then it does not detect the maps
    Have tried Garmin unlocker alternative 7.16 and 8 no joy

    Not sure if I did the factory reset before or after the downgrade which might be the cause perhaps?
    And seeing that it detects the locked map on the sd card the FAT32 formatted 8GB card is working fine?

    Will version 4.2 allow custom maps still?

    Sorry for all the questions and thanks for the help

    Edit:

    Sorted thanks!

    Did factory reset
    Reloaded v3.6
    Removed Card
    Factory Reset
    Copied latest copied of maps to card
    Used gimgtools-0.02-win32 to unlock
    Opened Garmin Homeport
    Deleted untitled.adm via Homeport
    Exported waypoints
    Insert into Garmin and powered on

    Working like a charm thanks this website contains a lot of great info

    Yep it does. Pays to look, eh. Thanks for posting the working procedure, much appreciated. Do you have version 3.60 firmware on both the 720 and 421s now, with custom maps working ok? If so, could you please post the firmware packs(s) as they will most certainly be helpful for other members. Post to any of these sites:
