Chris will probably find this amusing. After pissing him about asking for cruise, satnav and bluetooth quotes for my V35 S2, and crying about the price of about $4000, he suggested that I could get a local bloke in Canberra to do the job and save airfares. Well, I purchased a Kenwood DNX6140 from the states (DVD changed to region free and AM band sorted). I booked the car in for the work to be done not knowing that he had not received the parts from Chris. After 8 days (and $5500 total) I got the car back, obviously reassembled in a hurry, the aircon wasn't working and the airbag indicator had not been reset. The car was ok otherwise for half a day and then refused to start, probably something to do with the transmission control module as no gear position is indicated on the dash. After another 9 days I am still waiting for something to be done.
THEREFORE, get your car done by Chris Rogers and don't be cheap. Its amazing how one can get as old as I am and still make big mistakes. I don't know when I will get my car going or who I might have to get to do it or how much more it might cost.
