Hi Nick
i'll be there tomorrow in an E89 and so will petach, so you are not alone
Reference routes on the BMW routes option; I have gone through the process of converting srhutch's tom tom route to the BMW routes software for E89 NAV, so if anyone wants a copy let me know.
Had a few issues, had to get the tom tom routes and convert them into google maps first, (used TYRE) once I had done this I transferred them manually into BMW Routes software (based on google maps) pity the BMW routes don't allow you an import route option. Main problem I had was that BMW routes allowed me to save the entire route, but then refused to transfer to car with an error stating that one or many? of the route points / waypoints was outside the map :?
error was
Route transfer to your vehicle is not possible. The coordinates for one or more destinations could not be clearly determined. It is possible that the destinations are located outside the navigable map zone. Please correct your input data. Enter place, street and house number for all your destinations.
This just doesn't make sense to me as I zoomed in on all waypoints and confirmed they are on a road at the right place etc; so either there is a bug or there is a navigable are with two postcodes clashing for example- so in the end I spent hours delving deeper as I wanted to identify if this was a bug or something else, moving the waypoints slighty etc etc had no joy and in the end was successful once I split the entire route into two sections (1) start to beachy head & (2) beachy head to end,
I have yet to identify why this has happened and will talk to BMW software team about it next week
