BMW Service Manager / Add your own service history to headunit

[XuLeTZ]

Hi guys. If I use this will it just ADD a line to my service history or will it remove all my current inputs when I upload (do I have to input all the old service info)

There is no free software that will allow you to keep the existing service history.
All of them will get deleted so make sure you write the ones you currently have on the screen as well.
Make a picture of them with date, mileage and the jobs carried out and write them again from the beginning.
So you have to input all the old service info + the new ones that you want to add.
