Marlin -

Sorry.  Since I purchased my first Garmin unit when the model number was "12," so I've kind of stuck with that manufacturer.  I've not spent much time evaluating units from other manufacturers.  (My last two Garmin units have had mapping capabilities.)

However, a quick check of Lowrance web sites shows that they support software (MapCreate) and it looks like they have a Topo CD for Canada.  This is more or less where I started with the Garmin products.
