Same problem here with the wireless system, would drop the signal every few minutes and have to be reset. They set me a new wireless one and a hardwired one to try out. Same problem again with the wifi version. The hardwired one has not shutdown in over 4,000 miles. So I shipped the 2 wifi versions back. Cost of my system (cable, interface and software) at an FMCA show direct from Silverleaf was $395 last September and they set it up in our Phaeton. I run the Silverleaf split screen with Delorme Street Atlas on my Acer netbook.
