Its hard finding one without NAV in the UK, if you're talking V8 at least (which is the only X5 language I talk!). Also, DSP is not standard with NAV here, which I am glad for. When I bought my 4.6is they all had NAV but not all DSP, and I didn't want DSP as I plan to go aftermarket at some point.

FWIW, until I do go aftermarket, the mk4 system does "just work" as others have said. If I need to get somewhere it gets me there better than a MID unit would, thats for sure :lol: No its not fancy or modern either but with the map on full screen even when not navigating, it gives the dash some life and with 3d mode doesn't even look too dated.

I would have gone aftermarket much sooner if the car didn't come with the mk4.
