tzt14 won't start



Just installed a TZT14 and on power up the unit shows the initial screen with the green progress bar at the bottom. The bar fills from left to right as it should then it just sits there on that screen and never moves on from there. I've done the "clear all " thing but still doesn't work. I've installed many TZTs from stand alone units like this to multiple set-ups and have not had any of them do this. The power is good and the rest of the system is fine ( radar, depth, Nmea 2000, etc ). Any suggestions? Thanks, Dave
