One of the best mod's i did to the car except the re-map, makes such a difference and a great bit of kit whether you choose an LCD or LED version

The navigation is leaps ahead of my old tomtom one in terms of picking up satellites and obvoiusly has a larger screen which helps, a bonus i didnt know i'd get is it has also slightly improved the quality of my music in my car, radio is clearer and music generally sounds better
