Summary: I had to send the first one back and get a second one. The first one I received was broken...the on and off switch did not work. I had to remove the battery and put it back in for the unit to turn on. When it was on the electronics on it were all wrong. The calendar was in the wrong spot along with the moon phases...Unit was a total disaster. The second one I received seems to be working so far. Will have to wait and see.
Summary: Don't waste your money on this. I bought these because I thought they would actually work as advertised and what I have now are two GPSs with subtandard radios. The claim that this radio is 5 watts is rediculous. I cannot receive clear signals from other 530 users even 500 yds away. This past weekend I was floating the Missouri River and was about 4 miles up stream with a clear view of the Washington, Mo shoreline.
