Marine GSP

I use the Garmin Nuvi 550 with the Garmin Winni map. It works well and does not cost a lot of $$$.

The only issue I have with it is that it does show tracks on the screen but these can not be saved to your home computer and then reloaded at a later date.

Once the memory fills up it deletes the oldest track.

I use the Nuvi 500, which is essentially the same unit as the 550 with the exception on some of the maps included, I think. It by no means would have the same functionality as a marine unit but it works fine for my purposes. I do know you can save a route on the unit and call it up at anytime. I don't know of any reason why you couldn't then upload that to your PC using MapSource, but I've never tried it so couldn't say for sure. For that matter I can't say I can think of a reason why I would.

Anyone using the Standard Horizon CP300 or CP500? I am considering one of them for my boat. Also, any experience with internal antenna vs external? Is there a noticeable difference between the two?

Can you save the track(s) to an SD card in the unit?

With the Garmin 536 you can save tracks and waypoints to the SD card then transfer them to your computer via Mapsource. I have also been successful in uploading previous tracks captured with a different GPS onto the SD card then onto the Garmin 536

This is not possible with the NUVI 500

One of my best investments has been a $10 Navionics app for the iPhone. It should be available for others as well. I see it is available for iPad and Andriod as well.

I have a Garmin 440S with the 3D chip, but the screen and view of the Navionics app is so much better, I find myself using it more and more. Much better visual than the Garmin, more like seeing your boat on a paper chart.
