I've had the same handheld compass for decades, but I have to step away from a Jeep to use the.

Anybody know of a decent option that I can mount in my Jeep. I see lots of options but all of them have poor reviews. Anybody know of a decent Compass I can use inside a vehicle.

I am not looking for another app on my smartphone.

You will always have deviation caused by the of all the steel in your vehicle. A high quality magnetic compass will have adjustment screws to compensate for the magnetic influences of your vehicle.
To adjust you would head your vehicle in all direction and note the difference and make minor adjustments until most of the error is removed. A deviation table would be drafted with your corrections which records the error for each 15 degrees of heading, used onboard a boat or ship. A corrected compass is a must in long distance navigation using only a compass heading to steer by on open water. But is this really practical on a vehicle?
Using an electronic compass is more forgiving for vehicle use. Adjustment is easy and it will give general direction.
