Thanks!!
I have looked at a few, but they seem to get rather technical and then I glaze over and start to lose the will to live (traction control off, 100mph round that corner!!)
I'd rather have someone say - "Hey this system will fit into your 350z and give you MP3 playability via your steering wheel controls and only costs £200"!!
Sorry, but that is as far as I will go (I know my limitations and they are very limited) - alright say it, I'm buggered!!!
