topo vs regular map

[sherjatt]

i guess i am a newbie for asking this.  i installed canadian topo map on my unit. i dont know what the difference is between topo and regular map. is there a website where i can learn and compare about topographic? i am really interested to know.

also in and around toronto area traffic button (green) comes on and it keeps saying no traffic on route and yet the highway is jam stuck.

The traffic is a service provided by Garmin; it is sometimes right and sometimes not...
