Hi peeps, have mentioned it before but bvasically i retrofitted my sat nav through audi when i bought my car (didnt realise you could do it for £600 via ebay ) well anyway Audi proper striped me up and gave me the nav with the old black nobs... i wanna know.. is it hard to change them over? can it even be done? i think them two little chrome nobs make such a difference to the interior look! and i want it sorted! how about these hazzydays people?? im not good with anything like this.. too scared ill f**k it up!!
