Im working on a simple computer for my mitsubishi pajero gen1
I want to have speed monitoring on a lcd screen.
I know there is a pulsesignal from the speedo, but dont know if its possible to use this with my arduino, or how to do it.
So I was thinking to put a GPS module to it to get speed. Then I also can get lat/long and altitude.
Any tips of a cheep and easy to use gps module?
Best if it has external antenna, as my dashboard is metal and arduino is placed under it.
thanks!

Lady Ada has a nice GPS module that's 5V compatible and that supports external active antenna:
Don't know if its the cheapest (and you'll also need an adapter cable), but Lady Ada chooses good products in my experience.

@h_vestbo
Just wonder if below one meets your demand as well, they are cheaper than the above mentioned but from China.

I got the gps unit working with an arduino mega;)
But it gives me coordinates like this: 5936.681N, 547.789E
Easy way to get 59.611344,5.796477 ?

Well, set out in long-hand:
5936.681 * 1000 = 5936681
5936681 / 100000 = 59
5936681 % 100000 = 36681
36681 / 60000 = 0.61135
