I use a Garmin
176 gps/chartplotter interfaaced with the lap top. I have been very happy with the set up!
Well during the trip I would bring it in and use it as an anchor
. At one point it hit the floor. Unfortunately the display quit working, although the gps
part still worked. So i just used the pc for plotting.
When we got back I called Garmin
. They informed me that the unit was 14 months old and out of warranty, bummer, but they would fix it free of charge. 4 days later it was back and fixed
