I'm guessing WAAS is good enough for that.

I think about all of the GPS manufacturers have an option to turn the steering wheel. Don't know of any hydraulic kits for a 1086. I'd suggest to see what the dealers in your area have to offer & go from there. Cash & carry for a cheap deal away from home doesn't always get you any support when things won't work.

I personally prefer a unit that turns the wheel from the center or steering column vs. the friction wheel type.
