Omega Electrical and Audio Help / Re: 1999 CDX SAT-NAV question

This is interesting, as when I installed the Navi system in my Omega I had to configure it so that it knew the angle of installation of the unit -- so the gyroscope knows what the inclination angle is relative to the ground. A little gadget was supplied to determine this, easy enough. Likewise you have to drive around for a while to allow it to calibrate the speed pulses, presumably it matches these to the GPS signals to then allow it to determine the distance travelled for each pulse.
Mine also had a wire to connect to the reverse light so it would know when you're reversing! I didn't bother though, too much effort considering I don't make a habit of reversing for any major distance! Didn't seem to cause any problem.
What exactly does it calculate using the gyroscope? I guess it knows when you're going uphill etc, but how does this help?
I did very much like the built-in navi. As mentioned, no problems with poor GPS signals, and I also liked the way it faded the music to the back speakers when making an announcement. I also have a TomTom, and while it's very useful for swapping between cars (I used it on holiday doing an 800 mile road trip in California), the built-in is much more convenient.
