Only had the Kuga a week now and never had a car with sat nav before! Well, just used it in anger the last couple of days takin the kids to cadbury world and warwick castle and even without a user manual! (dealer still waitin for it to come in!) found it so easy to use and overall brilliant, although i have nothing to compare it too... but still, very user friendly, just played with it a bit to set it up! wack in the postcode and away you go...no probs.
The technology is 5 years old. So its not very user friendly. The most annoying bit is that it's DVD based. Not harddisk or RAM disk based as all the other GPS:es out on the market. So it's pretty slow. It's really annoying in some situations.
So the only reason to order the Sat Nav unit is:
* Looks good
* Great integration spot with all the functions in the car.
