Yes. There used top be a download at www.jrcamerica.com but I can't find it now. I bought the required null modem cable, used the intended J-NAV LINK 2300 softaware and still got the ERROR msg. If you figure it out let me know, because loading waypints/routes is very timely.

hi
You have lost your magnatron. The HighVoltage connection or the magnatron has gone bad. You have to disconnect the power to the unit. First disassemble housing and remove the rotor or disconnect the power to the rotor motor. Check for a burn on the insulation of high voltage wiring. This could be the clicking noise. In this case use high voltage gloves and repair the connection or replace the magnatron assembly. Please be careful of HIGH voltage. Note; hd sig miss could be decoded stating High Defined Signal Missing.
