Trip Computers for AUII

[deadly]

I have borrowed a GPS from my brother and it has a nice tool on it which shows you speed - what it is/average speed/total distace, Time - taken/total driven. I was wondering if Ford have one that I could fit from the factory and what calculations it would show.

Also can this be fitted by myself or would it be best for a qualified person to do this.

Please note I am in WA so anybody that I could see here in Perth would be great.
