GARMIN EDGE 800 need Help to install unlocked maps.
Getting message "can not authenticate the map". All maps (MapSource) are unlocked by JM 1.5 unlocker based on unit ID and perfectly working on other Garmin GPS devices nuvii 260 and Edge 705. Also, ive tried to installed alternatively unlocked maps ( unlocked with Unblock MapSource Directory v1.4) - no success ether, same error message.
Does anyone who owes EDGE 800 is experiencing the same issue? Is it crackable?
I have Edge800(U), and I would like to apply firmware of Edge800 Japanese version to it.
Normal way, copying GUPDATE.GCD into garmin dir, it's ignored beacuse of the difference of HW_ID.
So, I changed HW_ID by RGN_Tool.
It's ok until updating software, but after boot, stop with err msg "SYSTEM SOFTWARE MISSING". (I get back by RGN)
I think it checking Unit ID, but I can't find the address.
Anyone can apply Japanese firmware?
