Just a mistake in my previous message but important in this topic. We have a 332c and not a 334!! Previously we have the “black and white” 330 i think.

Hi every one on this topic. I’m from France and we use the LMS 334. Before we have the 332. We never have problems with those products just before this last Sunday. We were at the start of the sail race “La route du Rhum” from St Malo in Brittany to Guadeloupe. There were around 10,000 boats on the sea to follow the departure, really impresive!! After around 3 or 4 hours our GPS lost is position and say GPS unit device lost??!! We have load the last update available on the Lowrance web site (rev 1.9) but the problem of radar pertubations stills exist. Again we never experiment that type of problems before but in that case there were so many boats around us and could explain the lost GPS position. This race is only every 4 years and we think we can stay like this if append so rarely. In “normal” conditions it works. Hope that the next products (500 series) solve definitely this issue. Hope it helps…
