Side question. Anyone have this
Amazon.com: Super Mini ELM327 V1.5 OBD2 OBD-II Bluetooth CAN-BUS Auto Diagnostic Tool for Windows XP, Vista, Win7, OSX and Android: Automotive
Its a OBD2 OBD-II Bluetooth Mini. I own one. But i've heard people say it drains their batteries if left plugged in. I really hate to keep unplugging and replugging every day. Anyone have battery drain?
