Devices which do not contain suitable GPS hardware may work when combined with a compatible external GPS device. Performance depends on good GPS reception conditions, and may vary. Features, capabilities, and pricing may differ between platforms and are subject to change at any time. OBD functionality is optional, and would require a supported OBD-II interface device and a compatible OBD-II compliant vehicle. See website for details. Features and capabilities can vary depending on your device and other circumstances. Use of Live Streaming feature is optional and requires a premium upgrade. Services are provided as-is, and are subject to change or discontinuation at any time. This functionality does have privacy implications. Please see this app's online documentation and http://Live.RaceRender.com before enabling its use. Use of Live Streaming service requires an Internet connection, and is therefore subject to your wireless carrier and/or Internet provider's data rates. Continued use of GPS running in the background can dramatically decrease battery life.
