I have a Lowrance LCX-19C that I bought new several years ago and I have the GPS antenna which is WAAS-capable. I haven't used it much in the past couple of years. A fe months ago I took the boat out and I could NOT get WAAS on the unit. The estimated position error (epe) was alwas over 100 feet. Under normal conditions, the unit used to have an epe of about 10-14 feet. I did try to spray some cleaner on the connections, but that didn't seem to do much good. I also turned the machine on a couple of days later and the results were still the same. Anyone have any ideas?

Thanks,

Pete
