One option is to send it to chelton. Turns out you have to work with either a
Chelton or STec dealer to get RMA.


What they call a mnior repair is flat rate price of $1163. Seems pricey, but
considering how much already is invested in the system, probably cheaper than
converting to garmin.


I just checked with them for a similar issue. They will drop ship direct to or
from you, with the dealer written permission.


Number is 800 872-7832
