Look under the chart table in front of the captains chair for the seatalk box. Remove the wood panel. If you open the large white hatches on the back of the boat, you should be able to locate the autopilot motor and control box. It’s a tight squeeze, but you should be able to climb inside. Our 2008 system is still working fine, especially the autopilot. We had to send in our 12 inch chart plotter for new LED backlighting, but that was cheap compared to a new one. We also had to clean off the contacts on the wind instrument plug. That required climbing the mast, but the unit works great now. You might be able to salvage what you have. It will take a lot of work to upgrade to a new integrated system. Some of the cables run through the headliner and go through very tight spaces on the cabin side. I know this because I replaced my speedo/temp sensor. The temp sensor was out, and I wanted it to work, but it turns out the new sensor that I put in isn't very accurate anyway. I should have left it alone.
