ES128 GPS not reading external GPS ant

[rltrbill]

I have a new Raystar RS130 connected but my unit says internal GPS. If I turn off internal, it says no GPS fix. I did try restarting unit with internal turned off and it still says no GPS fix..... How do I correct to read the external?

Also, the selector know has to be turned 1 FULL turn to move to the next highlighted selection. Real pain to turn in 4 full turns to move it down 4 columns. This used to work fine (like 1/4 turn to move it) until I sent the unit for repair in Sept when Raymarine updated the software (to v15.91 I believe).
