GPS input
All, if you are installing a GPS, most cars require a pick up point from the speedo to assist with the satellite calculations. I was hooking up my Blaupunkt DX-N the other day and found that a provision for the SatNav was already there.
1. Take off the speedo shroud. Basically you just pull it toward yourself.
2. Take out the 4 screws that holds the speedo pod in. Pull out the speedo pod so you can gain access to the loom plugs on the back. Remove loom plugs.
3. The large white plug is the one you will be interested in. Hold up the plug so the retaining clip is on top and you are looking into the plug, not from the rear of the plug. Count 11 holes across and number 11 should be vacant. (the space is just the the right of centre under the retaing clip) This is the pin you will need to get a wire to. (The plug is 20 across x 2 down, Number 1 is on top left when looking INTO the plug)
4. I have some old computers at home that could be canibalised, so I looked for a small connector that goes to a motherboard. Pulled one out and checked for size,PERFECT fit! Put the connector into the loom plug, joined up the speedo cable on my SatNav to this connector, soldered and heat shrinked, all done.
Put it all back and hey presto, speedo input!
I've heard that taking a feed off from the speedo itself is too low a voltage, but because the point described above is designed for a Sat Nav the voltage is spot on. I ran a voltmeter across it doing 60Kms and got a solid 7 volts.

Re: GPS input
Good stuff Andrew,

Re: GPS input
I bought a Blaupunkt DX-N unit, only for the reason that it has a gyroscope unit built in. This means it works better in heavily built up areas where loss of signal occurs. Basically the gyroscope holds the calculation data for longer giving a better navigation experiance!
I work for a company who specialise in SatNav and their advice was that the gyroscope units were vastly superior to the hand helds. I've used Navman, Mio, Garmen, and a few others and they are all good. The beauty of the Blaupunkt however is once it fires up, it doesn't lose signal from the sats. (Worst case so far is running with 5 sats.)
My unit cost $600 (new) from ebay, but is worth around the $2000 mark. It does have a few small quirks that would not be to everyones liking, but hey, it does what I want, it get's me from A to B easily and without fuss. The only thing I don't like about it is I have to use the screen supplied at this stage because it utilises a VGA plug setup which is not compatible with my DVD/radio unit. THis uses a RCA input and I need to get a specialised adapter for it to work properly. Basically the sync is an issue. If anyone can help in this regard, let me know.

Re: GPS input
For reference, here is a photo that Andrew sent me showing the connection. The red wire is in Pin 11 (counting from the right) ...
Andrew,
I connected to pin 11, I get +12V when the car is not moving, have not tested it in motion. Is that correct? I would have expected 0V increasing to a max of 12V as speed increased?
