Garmin GPSMAP 76CSx GPS Receiver

Very happy with this GPS unit. We use it on the boat and in the car. The Micro SD cards are inexpensive. Blue chart software for boating charts and city select North America software is easy to download onto the unit. Can down load thru software prompts or Can also turn the unit into a harddrive for faster downloading. The unit should be updated every couple of months by using the Garmin Map source updater or going to Garmin web site,and the software should be updated periodically. Be prepared to have extra SD micro cards since they really don't hold too much. my 512MB only holds maps from Virginia to Florida.The technical support is awesome at Garmin. Hope this helps you make your decision.
