I have a Lowrance 3500C GPS (color GPS mapping) unit which I bought for $800 in 2005. The other day I started to get a "GPS Module Not Responding."
I downloaded a troubleshooting guide from their website. based on the results, it indicated my unit needed to go into the shop for repair.
I called Lowrance to schedule the repair. They told me they no longer repair this unit and tried to give me a discount on their new HDS unit. They stated there were no parts available anymore. What gives??
