Gwinnette United BMW tech is who told me that. But, I'll try the Matt at Decatur.

It just doesn't sound right that using a non-compatible phone can cause such catastrophic damage. I mean, it synched and worked for a good month or so, you know?

The tech told me that it may have worked just out of fluke. But after a while, it must have "jammed" up the software and caused it to go bazark.
