Summary: its manufacturer discontinued and not supported. no accessories available. bought this to feed a gps signal to my vhf dsc radio on my boat, it does not, and no cords are available to connect it.
Summary: Nice features for the money. The one I had was replaced 2 times in less than 6 months. The guy at Cabela's said they have had a lot of them returned because of problems that developed after they were used a while. The second time it went down I upgraded to a Garmin Legend and I'm a lot more satisfied.
