Thanks for the reply. We have a small Garmin for point A to point B turn-by-turn stuff in the city. I also have a hand held GPS Map 60C for carrying around with me. I was considering these units for the high visibility and outstanding Marine mapping that Lowrance is known for. I will get a cupholder mount for my kayak and use this unit there, as well. Finally, I have been reading about the modular sound system that can be controlled by this unit. I'd like to get rid of my stereo and change over to this iPod/Serious unit that Lowrance sells. I've heard that these are great units and am glad to hear that you like yours, as well.

Now to decide on the 7M or 5M. The price difference is staggering...

Thanks John.
