i've just bought an double din Eclipse avn2454 w/o the navigation disk. the only reason why i was ok with that was because i have a couple friends with eclipse navi systems aswell and figured i can cop a copy from them. the problem is my headunit doesnt recognize their dvd's

does anyone have any experience with this? the dvd i barrowed is the "north america ver. 1.2". i have done some research online and its sapposed to be compatible but there isnt much more info online.

 

nm found the answer

only 1.0/1.4/2.1 disks are compatible
