Ok, then I can forget the SD card version for me. What about the download version?
Of course if you BUY the official map download from Garmin it will work either in the device's internal memory or on an inserted SD card because it's licensing will be linked to the
Oregon's 10-digit Unit ID number.
To use the Topo map data which was intended for and licensed to a different device/SD you will need to use one of the following two methods*:
(i) Unlock the IMG file with gimgunlock v0.04 and then change it's Code Page entries if needed from 65001 (unicode) to 1252 (latin) using IMGTool. Test in device. If should work but without unicode features. To use unicode, unload the CP-modified IMG file and load the unlocked original IMG. All unicode features should then be enabled
until the next hard-reset of the device;
or
(ii) Unlock the IMG file with gimgunlock 0.04 and additionally treat the device firmware with IMGPatcher v2.20 (aka "Universal Firmware Patcher for Protected Garmin Devices") then reflash the patched fw to the device.
*First method only works if the protected device's fw has 'weak' MSV. Second method works for both 'weak' and 'strong' MSV (Map Signature Verification). Oregon 7xxx HWID 2512 has weak MSV.
Is it allowed to use other OSM/OTM cards on an SD card? I can't find anything on the net in this regard. Would be nice if someone could help me here.
I haven't tested on an Oregon 7xx but you at most may need to treat the IMG or the firmware as detailed above.
