    Default Map requirements for Drive 61 GPS

    Hello I have been creating maps (non routable) for the Nuvi series GPS for many years using MapSource and GPX2IMG applications and it has served me well.

    I am now trying to create maps for a Drive 61 and the maps are not loading, it appears they use a different map file format or possibly more.

    Could someone describe the Drive series map file format and tools used to create a map? If possible I would like to be able to make the routable.

    Thank You

    ~ Phil

    Drive 61 has 'protected' firmware which doesn't allow use of detail maps other than those either available as the device's OEM entitlement or legally purchased Garmin-issued mapping for the specific device. Unfortunately that also may mean that any third-party map will not be allowed either. On attempting to load unauthorzed mapping the device will probably show a message something like 'Maps are corrupt and cannot be loaded'. The only solution is to use Universal Firmware Patcher for Protected Garmin Devices however to do that for any reason breaches Garmin EULA for it's software even though in your case it mightn't technically breach their EULA for mapping data use.

    What kind of warning does your Drive 61 issue when trying to load such a custom map?

    Could you give an example of any such custom map to analyze the reasons for its rejection?
