    The problem is that if you're using your Landy correctly you're probably out of mobile reception!

    Doesn't matter - the GPS will still work and Google maps will show you what direction you're facing even when not on a marked road and have no signal - have done this plenty of times.

    AFAIR I tried 2 in my81RRC in Saudi.
    One was a radio Shack one which was supposed to be compensated.
    It didn't work reliably.

    I carry an orienteering type compass which you can take back bearings from in my console. To use it I would walk about 10 metres from the car.( but I never do)

    I love mapping/plotting /navigation , bring out a topographical map and I can be absorbed for hours.

    I have never gelled to the finger poking, pushing, pulling, sliding antics of gps/phone maps.....in fact I dislike it.

    What is the tactile sensory thing with rubbing your finger over a plastic screen and talking to a computer generated voice?

    Nothing like stopping , having a **** , spread your map out on your bonnet , pick a blade of grass or a twig for a pointer and scanning the country with your eyes and referring back to your map.....now that's tactile and sensory.

    I'm a bit of a dinosaur with this stuff buy don't you have to be moving for a GPS to tell you what direction you're heading? Otherwise, it knows where it is but not which way it's facing. If you want to be able to glance at something as a reference to which was is north etc, a compass is hard to beat. And a nice look in a Landy.
    In light aircraft, there will be a card mounted by the magnetic compass which tells you the deviation, or error, of that particular compass in that particular aircraft. It's checked at servicing by parking the aircraft on a reference line and seeing by how far the compass disagrees with the known direction. Usually only a few degrees. Then of course it changes with acceleration, overshoots or undershoots when turning, oh yes and there will be a variation between magnetic north and true north that is dependent on your longitude- iirc it's somewhere between 9 and 11 degrees over most of Aus but it changes each year....ahh the memories.

    Yes, yes, yes!

    Exactly why I have a stash of maps in the overhead console (of where I'm going) and a Silva compass in the cubby box.
