March 28, 2015Don’t listen to comments ABOUT “NO MAPS”!!! They are without merit.,
These units come with a typical MAP,…just like an auto GPS. And just like an auto GPS, you have to continually update it.
Now,…you ARE given a choice as far as your update functions go. You can either update the version you have on the gps,..just like a car unit,…OR,…you can purchase a Vision Map card with much more detailed info and also open up additional navigation and routing options. Does this mean,..it’s a scam? Of course not! It’s like any other business. There are upgrades for those that want it and can afford them. Even if you didn’t have the additional upgrade of the card,…you could still utilize the unit,…BUT,..it would be nicer if you had an upgrade card because it opens up a wealth of information(tide charts, different navigational routing methods, hi-res graphics of landmarks, etc, etc, etc).
And another thing,…since these people are so quick and eager to badmouth the purchase of an upgraded map card. If they did their homework,…LIKE I DID,…they would have realized that when purchasing any one of the line of these particular units,…you could have received a full $200 rebate on buying the unit and card at the same time. So,..my $212 upgrade card,..ended up costing me,…$12.
Do I sound somewhat arrogant,..maybe,…but,…someone needs to be real here!!
As far as the unit’s functionality goes,…the unit is brilliant. I boated a 4+hour ride from 9pm til 1:15 AM,…..and had NO difficulties in navigation with this GPS,…along the coast,…through canals,…under bridges,….easily navigating through channels and markers,…all at midnight, relying on this unit. It was freakin’ dark, but the unit (along with my G2 Vision card), was able to foresee the channel markers, buoys, landmarks, that were virtually invisible to me in the dark!!!!!
Oh yeah,..did I mention it was in a pontoon boat!! So, do yourselves a favor,…..DISREGARD the negative comments. They are WITHOUT merit!
