First of all, lots of thanks for such a valuable stuff.
i have nuvi 1410 which is capable of Junction View. I did not find \Garmin\JCV folder. I created it and pasted the JCV file but i did not get the view onto my nuvi.

Can u pl help me out?

regards,

how to install it on a garmin streetpilot c340 device please

StreetPilot c3x0 can only use a detail map file under 2GiB in size named gmapsupp.img in an SD card's root folder named Garmin (i.e: X:\Garmin\gmapsupp.img). You cannot load a detail map to it's internal memory.

This is a very old thread with dead links anyway.
