it was just over 1k
without digging out receipt - i think that where the dealer hasnt done one before they may be willing to negotiate it down - as it happened with mine,the first attempt to fit it failed - and required a link to the mothership in germany to get the software to work, but i think that was down to it being so new and dealer not having done one on an f10
so worth checking out a few - as i recall cotswold bmw gave a competitive quote - if its worth a day out!
hope that helpshttp://f10.5post.com/forums/images/smilies/thumbsup.gif
