I've recently purchased a Blaupunkt TravelPilot RNS2 system that was removed from a Honda Civic. I would like to fit this system to my '95 Saab 9000 Aero, and was wondering if anyone had any experience of fitting one of the Blaupunkt units to a 9000, or could recommend a good installer in the London area?

Specifically, I'm interested in knowing whether the speedo signal is brought to any of the pins on the radio interface (e.g. to connect to a radio that varies volume with speed), as a speedo input is required for the GPS head unit.

Many thanks for any help you can offer.

Shouldn't the GPS unit work out the speed itself, it does on my Laptop. The EDU unit has a speed feed to it, search for the thread on this or the SCC unit as a recent post listed the connections and what they carried.

The GPS units need a speed sensor so that they can continue to plot your approximate position along the guided route when the GPS signal becomes weak e.g inside a tunnel when you've got a turning maybe only 100m or so afterwards.

The speed signal is available on the green wire of the two 8 pin connectors that go to the DCC unit.

So do these GPS travel systems have an auto calibration function then?

I assume they must as all manurfacturers are going to choose different numbers of pulses etc per mph just to be helpful...

According to the instruction manual, the unit I've purchased needs to be calibrated. Takes about 15km before the system is set-up properly.
