Compasses that work in rvs

stay away from the speaker magnets.

I have 3 OBD II adapters, all 3 are "no name" if you go to the proper page in the Torque help section there is a photo of a "Cheap E-Bay adapter" that usually does not work.. the one I have that works looks exactly like that one.

The other two are smaller and will not connect, they pair up but will not connect,, I will work with them more later.

This is the one that worked

Though I can not guarantee it will work for you.

PM me for a less expensive way to buy it (The method I used).

Not to hijack the thread, but what kind of OBD-II adapter are you using, I've got the torque app, but haven't gotten the adapter yet.

I have three that seem to work well in my coach and car.

Two are "Flux Gate" they do need occasional calibration (Push proper buttons and drive in a circle) but they work well.

I also use a couple apps on my cell phone.. one is Compass (Free) and the other is TORQUE (pro) one of the widgets is a GPS compass.. Dead accurate plus/minus so little you'd never notice it. When I have my primary "Glass Dash" up the phone, tied to my OBD-II adapter shows RPM, Compass.. Coolant,, Voltage,, Engine load, Timing advance and manifold pressure/vacuum. Other pages show other things if I wish (one way to calibrate speedo is use GPS speed, OBD speed and Speedo Speed) Rather handy app. But you need the hardware.

Most any GPS. even the cheapest Garmin E-Trex. Will do compass.

I wouldn't advise an aircraft compass; if you really want to use it, you'll be swinging it and adjusting the reader card quite frequently.

I have a compass in the PA-12 because it's required by the FAA...and I adjust it as frequently as required (even though a PITA)...but what I use for navigation is either IFR (I Follow Rivers) or the GPS.

I have used a small boating compass very successfully in previous vehicles. :)

I picked up a $5 radar detector with compass built in. If I ever need better, I will get GPS

Both the temperature gauge and the compass are very accurate. The compass has saved us many miles of traveling in the wrong direction.

This is what I have as well. I like all 3 features.
