From my understanding (and this is just from reading info on the AVIC-Z1), the Z1 uses the speed sensor and an internal gyroscope to determine your current location if you lose the GPS signal. Once the signal is reacquired, it syncs to where the satellites are saying you are. It continuously records this information and the unit becomes more and more accurate the more you drive. So if you are driving in a heavily wooded area or in the city with tall buildings it can still maintain a high level of accuracy.

One more quick question. Where in the engine compartment is the PCM located?

Ok, that makes sense for the need of a speed sensor. However, not sure how often it would be used on the main highways of the US. I travel with a Garmin iQue 3600 for the roads, and I have only lost signals in very narrow canyons for a few minutes, or in long tunnels.

PCM is at the left rear of the eingine compartment, by the coolant bottle.
