hi
Theres no easy cheap way, but if your cars a keeper, I bought Jagdroid, its your old touch screen updated to android and every thing you can do on your phone you can do on your touch screen
plus all the oe stuff still works fine, like acm, jaguar voice, climate, cd player, cd changer and still looks oe
plus you can have usb plug and play for mp3, front and rear cameras, internet, spotify, dab , google maps, stream music from your phone and lots more, but its not cheap
had mine a few years and love it
