Can someone help. Is it possible just to change the ECU on a 523i to bring it up to a 525i. Is there anybody in singapore that can do it? Secondly is it possible to buy a Sat/nav and/or cruise control system that doesnt look like an add on or an attachment'.
Both are considerably expensive if you go for the BMW path, ie factory fit
