Here is my situation
I have a 73sv with map version dated last year. I just purchased a Chirp 93sv and an Lakevu Ultra Card The installed maps on the 93sv are the most recent version. I downloaded the maps from the 93sv to a SD card. I took that card and then put it in the 73sv and was hoping to update the maps that way. It does not seem to see the maps on the card and cant find an option to download from the card.
I checked user date option and the only file it recognized was waypoints that I also have saved on the card. I then took the card and viewed it in Homeport to verify that the maps actually downloaded which they did.
Any Ideas?? Thanks
