what is the difference in auto vs. motorcycle ??
New here so sorry if this has been brought up before. I have a Garmin 450 with city navigator MicroSD installed. what is the difference in routing between auto and motorcycle ? does it pick different roads ? what is the criteria for routing? anybody know or have an idea ? I use this unit on my motorcycle, so it would be great if it always picked 2 lane highways or something like that.
