We use the Standard Horizon 175C in our 31. It is the next size up from the 155C. Outside it is 9.2" across and 5.6" high. The screen is 4/6" X 3.4". At 85 MPH you can still see the colored screen and know where your going. It uses the C-Map NT+ C-Cards. Happy Shopping!!

Send me the old one...got any chart maps for it?

You still want to buy the old unit. Lowrance 2000 Globalmap. the only chip I have is for NJ.

I looking to buy a new gps for my 358. Anyone know anything about the Northstar with the Smartcraft?

I installed a Garmin 440 . At first i thought it would be too small . But surprisingly it works great . My dash space is very limited on my Top Gun . Great price and the G2 Blue Chart has great detail .

Hey 1bagger, how do you like the 440 now that you have been having it a month or so? Ive been torn between the 276C and 440, but leaning towards the 440 since the detailed maps are built in.

Went with the Lowrance 7200C. Almost fit in the hole that the old one came out of. Had to cut aboout 1/2in to make it fit right. Works great and visible in direct light.
