Help with Holux GM-82 GPS module

As one of my first projects I would like to connect my GPS receiver module to Arduino. I bought it a year ago, but I have never used it.
It has a lot of connections compared to popular modules used on most shields. It based on Sirf GPS2e/LP-7450 chipset.
I downloaded the datasheet, but it's to messy for me.

I have a little hope that someone here had experience with this piece of harware.
