the hardest bit to remove was the plastic cover by the satnav screen, it will take about an hour if you take your time, i was surprised how easy it all came apart and back together again. i wouldnt have done it if it wasent for the 'how to' and dont forget the 2 screw at ther bottom of the head unit, ive now got one
ive opted for the full ipod set up which will charge the ipod and give me control of the ipod via the steering wheel,etc and it also as the a connection for a standard AUX input as well so a standard mp3 can also be used if needed, so the best of both worlds.
just waiting for it to come and i will post how good it is.
