Sigh, I'm £189 lighter and the issue remains. Albeit it got very confusing. I got handed back the keys today, 'there you go mr , you now have 2012 maps' I said er yeah, it had 2012 maps when I brought it in! They look confused and said but you wanted the map update. I said No I had the map update, I wanted the nav software update to hopefully fix the map issue. They said yeah it's been done. Lots of confusion later i clarified that I had the map update but wanted the cars systems updating. I showed them the fact three manchesters still showed on a search, they checked on a 5 series and that had two manchesters listed!?! So as it turns out the idrive was updated weeks ago when I had the dct done. So ive had new software already.. Which the 2012 maps don't work with properly, looks like a mapping issue full stop. So now for a battle to get my £189 back as in essence they did nothing I didn't already have! Sigh sigh sigh.
