Hope all is well. I have the Garmin GPS MAP 295, whih is the pilot version of the "Street Pilot". I have a permanant mount in the boat and one in the Excursion.
I installed the remote antenna under the dash of the boat and it works great thru the fiberglass. I installed the receiver/color screen just to the right of the throttle, under the side of the boat to keep it out of the direct sunlight.
It works great. I purchased this model primarlary for flying, but because I travel all over the USA, Canada & Mexico, I wanted something I gould use in the car as well. It also shows great detail while in the boat.
You can upload detailed maps to it with a PC using a 128K removable chip.
I have it mounted with a gimble attachment that lets me tuck it way under during sunny days and lets it swing way out for night use.
I'll send you a pix of it later. I am off to Mexico City tomorrow. Be back home on Friday.
Talk to you soon.......CJG.
