They do not use Navionics but use Garmin's own G2 mapping. They have the new LakeVu HD and LakeVu HD Ultra mapping available now for Canada and many lakes are in HD.

Garmin is certainly worth checking out now for the fishermen. Due to the lack of imaging sonar options in the past Garmin was often overlooked. They are our #1 unit for pleasure boaters because of the high GPS quality and the extreme ease of use. Now with the improved sonar options the fishermen can take advantage as well!
