And for the sake of about £600 to fit the RNS-E (DVD Sat Nav) I'd just go with the Concert for now. There's no difference in sound quality between that and the Symphony, but the RNS-E sounds a hell of a lot better.
If it is, that's news to me. I tested the Concert and Symphony in demo cars before I ordered mine and they sounded identical, so I just ordered the Concert. When I swapped it for the RNS-E it was a similar difference to when I took the factory unit out of my 2004 Astra SRi and put it in a £650 Alpine head unit. With the concert I was thinking of fitting some amps and upgrading the speakers, as soon as I turned on the RNS-E I thought all that could wait a while, no rush now.
Stndard fit concert 2 plays mps as well, listened in the showroom to a car with the Symphony fitted and could not tell the differance. Interested to see if the RNS-E sound better - Cant seem to get the Concert loud enough for my liking !

I'm never convinced by factory stereo upgrades anyway. For example i've been looking into my new car options (starts with a B and ends in a W)... The factory options are a total rip off. I'm thinking i'll upgrade the speakers myself in time and fit a new head unit for a lot less than the dealers are quoting....And it'll sound better.
