Scirocco Central

Hi all, I currently have an rcd 510 screen but my Bluetooth doesn't work and there is no box present I bought a Bluetooth box on eBay for about £150 and I was wondering if anybody had any tips on fitting it or whether it would work and if I need my rcd 510 updating, my is a 59 plate 2010 if that helps
Thanks guys, any help would be appreciated

there is a bluetooth retrofit guide on the website. Just search for "bluetooth retrofit" and it should pop up
