Go with the internal antenna. It is one less cable to run and one less connector that will get corroded. It also saves deck space for mounting other gear.

Cant argue with that logic. Thanks

Internal antenna is better, external antenna should not be a problem. I got an external antenna GPSMAP 178 unit without the antenna. What I did is I got a BNC connector from RadioShak and connected a piece of copper wire to it. Done. No WAAS but good enough to 20 ft accuracy. It'll do untill I get a cheap antenna from somehwere. But I asure you, you can't go any cheaper than this! The only caveat is it takes very long to get a consistent 3D signal.
