SAT NAV, deffo!
It adds that little something over the non-sat nav version, with better controls for your climate control and audio. The voice control is a bit naff, but i'm a brummy and it works ok for me. The nav threw me to start with (i was a tomtom user) but i'm used to it now and it's not let me down yet...
The
HFT is OK, not brilliant, but better than ripping the car apart to fit one later on.
Rages look mint, but give it 12 months and they'll be available on ebay (thats what i told myself anyway!)
As far as the ipod connector goes, i see no evidence of a better all-round cheaper solution so far (i await my flaming!).
It's an expensive toy, but if you add up a decent tomtom,
hft, 7" screen, & fitting, i bet you wont be far off!
