im pretty sure we have the 172....had it about a year..stil havent been able to hook it up yet thou..does anyone know where to get the template for mounting it flush in the fiberglass? we kinda lost ours thanks and sorry to hijack thread

Hi ! I've had the 176c for about 4 years. like it, but should have bought the 182C.
One problem is you really can't follow it bouncing around going fast, so buy one with a bigger display.
Basically the Garmins are all similar , and you pay alot for a big display.
Has anyone tried interfacing a Garmin with lets say a Sony 19" lcd monitor, I've heard it can be done.
Garmin is D-Bomb ! BBB

I have the Blue Chart data card for southwest Florida ..NEW never used if anyone is interested. Fits all Garmins

I think the 178c has a depth sounder added which might be nice.

I have been thinking about upgradubg my 276c to this one I know its prelaoded does this mean all the charts are unlocked and how do you upgrade the charts when they are avaiable?
I am going to put it where the compass is now.
I always carry a spare compass anyway.

All the Coastal & Great lakes charts are loaded & unlocked. It will also
accept the data cards. I dont know about upgrading in the
future

great unit I have installed many of them...only draw back is that it doesnt use the c chip you have to buy garmins chip/data card

I like mine

I've had a few Garmins over the years and no complaints. The one I liked best was the 2006C in my old boat. I just purchased this one; http://www.garmin.com/products/gpsmap376c/

Birdog, how much for the chip?
