Yes, you can likely extract the HD images from the dumped BIN file and write it to the Garmin BIN using GIR_Editor. I say likely because i'm unaware of the type of images used by those devices and some later types of images aren't able to be saved from BINs with GIR_Editor. This thread gives an example of how to do the image changes in the BIN file: [Only registered and activated users can see links. ] (for general information only).
