I need help to unlock this device, thanks .
A simple search would have found multiple posts listing devices that cannot be Patched, the rule of thumb is you can't find a patch using your HWID 3286 in your case in "serach this topic" then it can't be patched.
For a few years newer device's firmware could be patched (determined by their HWID) to use unlocked maps, since the DriveSmart 65 the firmware has been encrypted on these later devices.
Unfortunately it looks like Drive, DriveSmart 52,55,65,66,71,76,86, zumo XT ,Alpha 200i, Montana 700 ,GPSMAP 67 & 67i are all in the same category.
No solution as the Universal Firmware Patcher does not recognise the new encrypted format.
