An expensive piece of kit which does not switch between international/USA and Canadian vhf channels. Useless for international travelling and atlantic crossing yachts. Clearly America and Canada are not international. Does it really cost that much in China for the extra electronic circuitry?

Also it might have AIS, but it has no way of displaying the info without a chart plotter and no info on set up ...unless you happen to have a Garmin chartplotter!. And you have to programme the nmea reception you require...page 30 in effectively a 34 page manual and no prompt; just no position info available; which is why you spend time checking all your connections and going slightly crazy.

Apart from that, which is why I purchased it; neat and easy to fit and user friendly and covered up the holes left by my Sailor vhf handset....another piece of expensive junk.
