Wow. what can i say. just got it fitted today for £570 by ttint, Luton. yes ive heard cheaper by some people but hey.
Only problem is that looking at the dvd players for other car makes and models, just wish the vxmmi screen can bit just a little bit bigger and i wish it didt sit so low, (astra's fault).. its great for your passenger Sat nav is good, dvd is great, sounds is better, installing digi tv to it soon, i'll update you on that.
stay away from the cheap china and hong kong units. most of them only come in grey unless you want to waite forever to order silver or piano black and some of them you have to download your own gps software and, it does take a wile to install the unit, took ttint an hr, would have taken me 3. nice bunch of lads and they make dvd players for other cars too.. Cheak them out..
