The other day as I changed ATC units the baro pressure changed from 1010mb to 1008mb. However my AF4500 would not let me set 1008, it kept jumping between 1009 and 1007. In the end I gave up and accepted the altitude reading was 30ft out.

Has anyone else seen this kind of problem? This is the first time it has happened to me in 2 years and >100 hours.

On a completely different subject, I have to change out my GPS feeding into the 4500 and am considering using a AFS 73101 remote GPS. Is this 'plug & play'? How is power provided to the GPS?
