Works as intended. Excellent support.
This lite version is intended only to check compatibility with your vehicle before purchasing the full blown version. It works flawlessly for that purpose and is compatible with my 07 X5 but not my 2000 E38. Online support was truly excellent and Parvis (the developer) responded to my email within 30 minutes (from Germany). The problem with incompatibility on some vehicles is that BMW uses a different communication protocol on those vehicles and none of the available wifi/BT adapters can support that protocol.
Bottom line, rate the software for how it performs its intended duty, not whether it works with your specific car. For that, its five stars!
