GPS unit

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.

thank you;)
that one is perfect!

@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 ?

Divide by 60? (plus appropriate powers of ten)

how do I do that i arduino?

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

thank you;)

still working on this.. feel kinda noob, and well I guess I still am:P

anyway, have tried to calculate this in arduino but dont know what variables to use etc..

Is this simple to make for anyone wanting to help me?

Have you tried using the TinyGPS Library.

I have attached it for your convenience
