the GPS and internal system so that it could be sold to third parties (possibly insurance companies). Although this data is supposed to be "anonymized", exactly what OnStar means by anonymizing GPS data remains unclear, and it may be impossible to make the data actually anonymous. A few weeks later, after outcry from subscribers and privacy advocate groups, OnStar reversed the decision to continue collecting information from unsubscribed units. A 2019 experiment hacking into the data collected by a 2017 Chevrolet Volt revealed that the car stored logs of calls made from the user's cell phone, as well as location and driving data, which could then be sold to third parties. Advertising campaign In 2000, GM produced a series of Batman OnStar commercials that featured Batman (using the Batmobile and props from the 1989 film) using the service to call people, access his mail, navigate to certain locations, and to unlock the Batmobile. These were discontinued with radio commercials. GM promoted the service with radio commercials (called "Real Calls") demonstrating how it would work. It provided the recording of someone interacting with OnStar in various scenarios designed to show its utility. The commercials stated that these were recordings of actual instances of customers using the services, and gave the date on which they occurred. From 2004 to 2009, OnStar was a sponsor for guest appearances on ESPN Radio programming, dubbed the "OnStar Hotline". In September 2010 under then-President Chris Preuss, OnStar relaunched its brand with a series of commercials with the theme of "Live On". According to Chief Marketing Officer Sam Mancuso, the campaign was designed to change how people view OnStar, "It's not about waiting for something to happen but something people can use every day." From 2008, OnStar has offered "Santa tracking" in all equipped vehicles around the festive period. This has allowed children worldwide to see Santa's location on Christmas Eve. Each time this feature is used, OnStar also made donations to various charities. Hardware GM is currently deploying OnStar Generation 10 hardware that includes enhanced services and diagnostics and the ability to use the mobile application RemoteLink, which allows a subscriber to perform many functions without the need for calling into the OnStar center. Functions include remote start, remote lock and unlock, flashing lights and horn as well as viewing up-to-date diagnostics data from the subscriber's iPhone or Android-powered mobile phone. As of 2011 OnStar hardware
