If you reset the GPS system, you should keep the car still for up to half an hour with the navigation system turned on, until you get at least three satelites. Only then you should drive the car for a while, then to calibrate the MK system.

When a GPS system (any GPS) is reset, it might take a while to download the "catalog". The same happens if you turn the GPS off in a location and turn it back on is a remote location (like when flying somewhere). The "catalog" is like a star map of the GPS satelittes that the GPS needs to know to discover the next frequency to listen to. In simple words, of course.

Well, I tried it today and got what I thought some progress. A couple of times I got a "Satellite Contact" but I've had the nav on for over an hour and now it's just sitting on "Satellite search" It can't be the antenna can it? The same unit does the same thing on my other car. If I put the "working" one it works...that's why I'm coming to the conculsion it can't be the antenna. and the number of satellite count is still at zero. Even when the Satellite contact showed a couple of times.
