Thank you so much for working with me, dasilvarsa. I have done exactly as you instructed but still no public transport capabilities. On the Navigation screen where it says "Transit Types", the button is chisled out, although it does say "enabled". Still, I am not given any options to use public transport of any sort.....the Nuvi 1300 does provide a pedestrian walking path to wherever I set it; but no public transport. I am using the FID800 catymag has supplied in post 8 and the name of the .img file is the exact same as the .unl file I generated using the 1.5 Jetmouse: However, no public transport. Both the .img and .unl are in the MAP folder on the SD What am I doing so wrong? I really am dependent on the transport or I wouldn't be pursuing it so much! Thanks.
