Hi,

I have read a lot of thread about ST5000+ but it hasn't solved my problem.

Basically the AP rudder reference bar starts to slip even though the rudder is straight to stern. Whenever you switch the unit on it can be from dead straight to showing 10 even 30 degrees out, again with the rudder straight to stern. When the AP is then set to auto and under sail, eventually it puts a full turn in and has to be switched to stand by.

So I've tested the compass and rudder transducer according to links on the forum and the resistance readings are as expected. Which makes me think the AP unit has gone faulty.

Could it be the transducer?? I could replace that but if i then need to replace the AP, the new transducer has been a wasted purchase.

I have read that the ST5000 can be replaced by the EV-200. When I have researched this it seems I am buying 3 components and Im not sure if the is correct for my Bavaria 37. The kit I have seen includes a a P70s, ACU-150 and EV1 sensor core, are these the components I would need?

Would my existing rudder transducer, compass and hydraulic ram connect to these, also would this work with the ST60 wind and depth instruments? My plotter is an RL70c pathfinder but I not worried about connecting to that as I use Navionics on my iphone for navigation.

If there is a solution that combines a new AP with plotter that I can have on the helm I would also be interested but again will this involve changing all the instruments as I assume the uo to date equipment us a different sea talk.

Any help would be appreciated.
