So I registered to try and get the Garmin Nuvi 1300 to display speed camera traps. I downloaded a couple files and put them where I thought they should be in my garmin's directories. However, no such luck.
Is there a really detailed step-by-step guide that pre-supposes nothing that'll help me do this properly? Not sure how I should be doing this - with a tool of some kind, when I plug in the USB cable not sure how I managed to get the garmin to come up as a drive on my Mac. I'm futzing. Any way I can reset my Garmin back to normal to delete the random files I put on?
Please - somebody help a noob.
