Thank you for contacting Sensis.
Unfortunately we do not provide the mapping update compatible with your 2005 BMW vehicle. For further information and assistance on the update you require, please contact your BMW Service Dealer/Head office or GPS manufacturer.
Whereis Pty Ltd provides the raw mapping data for the manufacturers such as Holden, Audi, Mercedes, TomTom, NavMan, however, once the manufacturers have the data, they then convert it to the format that suit their machines.
We thank you for your time and apologise for any inconvenience
Should you require further assistance or for further enquiries, please do not hesitate to contact us on: 1800 819 471.
So i would be careful jumping into buying one unless you are sure it will work.
