Navteq is the supplier of map DVD's for Ford. You should check out their website and see if there is a European DVD you can purchase or find on eBay. Otherwise, your only other option is to buy an aftermarket navigation system. There are many double DIN units that would fit, check out www.crutchfield.com

If you accelerate quickly or do not drive smoothly, you could easily do worse. Other factors are carrying a bunch of extra weight around or having under inflated tires. Lastly, you have a Front Wheel Drive, right? The AWD is even worse.
