Mike,
I bought the HDS-5/GPS last summer. I'm running the Navionics Platinum Hotmaps region 7 on it. Thing works great.It comes on an SD card that you just pop in. The door is on the lower right side of the unit where it says HDS5. Just open that, put it in, start the unit and I believe under one of the menus(can't remember where, long winter) you choose the maps. The maps are very accurate but missing some markers. I have the LGS 4000 antenna for it because the unit is under my T-top but never did get to put that on last year because the unit worked well without it. Plan though to install it this year to see if it makes it more accurate.
Just bought the Stucture Scan unit for it so waiting for that to come and install it before iceout.
let me know if you need anymore info. Good luck with the unit.

thanks a lot for the feedback guys...great link for the HDS. While it may take me a little while to recover from this purchase and start looking at Navionics chips, I did browse the Navionics website and a few retailer sites and there appear to be several choices of navionics chips available with options like:
-entire US vs just East (I only need northeast)
-2D vs 3d
-Gold vs platinum
I'd like opinions on which card you use and if you feel upgrading gold to platinum or 2d vs 3d is worth it...which chip would you buy for your HDS and why?
I want to make an informed choice from consumers not bite on the manufacturers "pitch".
