I was going to say the same
An autopilot is a highly desirable feature on a VFR Xcountry bird and almost essential for IFR, plus the nav head gives you ittitude infor as well.
Of course the first question is..why do you need a backup..IFR..sure combine it with the autopilot, makes sense.
For VFR the best gyro you got is your eyeballs.
