Will the units with the internal GPS+WAAS antenna be affected by the t-top or do I have to have the external antenna?
I have the garmin 176c. the little one.. I have it mounted near the helm and it has always had a clear signal. They make an external antenna that hooks up to it, but I really dont think its necessary.
I ended up picking up the eagle 2000C W/GPS. Tight 7 inch screen and color. I am done shopping. I just was not happy with the GPS that is in the boat and figured I would get something a little better. I will move my other depthfinder to the front of the boat and will sell my GPS. thanks for the help bret. Keith
