Mine and a friend's does the same thing! Mine has been back to HB once & it's still screwed up.

I'm pretty sure you can add an external GPS antenna but that an added $140!

This is the 2nd unit with an internal antenna that I've had to send back. I'm about to give up on'um.

Nope... Clear view mounted on an 11" pedestal.

I just wanna know what is the difference in the 2 antennas in case I wanna go that route.

I think the AS GRP is just the new name for the AS GR50....

(The HB website does not show the AS GR50 anymore Accessories :: System Modules :: GPS Receivers :: Humminbird)...

The AS GPS HS will be a completely different antenna....(http://store.humminbird.com/products/604403/AS_GRP -click the down arrow next to the AS GRP on the HB website)...

Terry...you may want to wait until the AS GPS HS is available....it's supposed to have the same accuracy as the AS GRP, but with an added "Heading Sensor" which will allow the boat icon to continue to show pointing in the direction the heading sensor is pointing even while stationary...(notice I said the boat icon will "continue to show" not "boat icon will continue to move"...)

of course the cost is more for the last one. they almost read the same except the ASGRP says it doesn't work with the Interlink

The differences are internal.
Operationally you should not notice any difference.
