I know many people here do not like Boat US/west Marine, but here it is anyway.<br /><br />Getting my boat ready for a 10 day vacation, I fired up my chart plotter. A Navman 5100 b/w unit. I kept telling me No GPS. In the begining of the season, I had to take the antenna apart because of a problem I created when I istalled it. It was the same problem. <br /><br />I decided rather than repalce the antenna ($130) I would buy the Navman 5500 color unit ($375 after price match and rebates) <br /><br />I looked on the Iboats and other places on the Web, the biggest problem was getting the unit in time with out paying a small fortune in shipping. <br /><br />So I called Boat US, and the one I called did not have it in stock, but referred me to another store only 10 minutes further from my house. So I went and bought it and they did match the best price I found on the web.<br /><br />I installed it, and started having problems with it just shutting off. On closer inspection I noticed that the connector for the power was cracked. I called the west Marine store where I got and they did not have any other one in stock. I explained, that I was leaving on vacation in 3 days. The gentleman I was speaking with, check the computer, found another unit at a close store, and had it shipped next to thier store. He will also allow me just to bring in the broken part, so I do nat have to remove the antenna, or wiring to make the swap.<br /><br />On a scale of 1 to 10, I have to give them a 10 in customer service.
