I am thinking of retrofitting my 2004 S4 with Sat Nav (the RNS-E system), from its current 'concerto' single CD radio. I undertstand that as it is going from a small slot to a bigger one it takes a bit more time and the conversion is more expensive - but where in the South-East can this be done? I came across a place in Bradford but this would mean a day trip for me...any tips?
