maybe i'm having a brain fart but i can't get it to work for me. ...or maybe it's dosen't work like my 60csx. i created a route in mapsource > uploaded to 500 > imported it from data > and it shows in custom routes. i selected it and it routed just like i wanted it to go. working as expected. i'm in my car so you know. now i diverted off the route about 30 minutes (no gps needed) and spent the night. next day i select the route again from custom routes and it asks if i want to navigate back to the start...no just continue from here. get me back on the original route. my 60csx does this with ease. it takes my position and gets me back to the closest point on my intended route and continues from there. anyway it would not show a route where to go? wtf? am i doing something wrong or is this a nuvi limitation? i also had my 60 and it took me back to my original route and i continued on. only when i was back on my original route did the 500 show where to go. i used the new route feature in the 500 and selected my destination city and it routed me there, but it's own different way. i did not want to go that way. i turned off the 500 and used the 60 in my hand till i was back in sync with the nuvi route. ...so is this how they work or am i doing something wrong??? is there another step i'm missing w/ the 500?
