Review on ICarsoft Professional Multi System Multi Brand Transmission by Caleb Quade

The first thing you need to do is update the firmware so that it recognizes half the systems in all cars newer than 2010. This can cause headaches. Thankfully, customer support is quick to respond to emails. However, he claims to be from a "US Headquarters" guy, but from the hours he responds and his slightly broken English, it's likely Chinese customer service. Even after the upgrade, I found that I couldn't run some of the declared functions. It doesn't seem to be able to actually complete the BMW battery registration or Chrysler oil reset. For the price of this device, I could buy multiple readers for different makes of car, but I wanted one reader to work with all makes of car. I do not recommend this brand. It might work for you as it has good reviews but I've had no luck.
