Please DO NOT plug your TRX7 CS into your vehicle's head unit.
Power output on your vehicle's head unit is not designed to charge large mobile devices (e.g. TRX7 CS Pro and other larger tablets). Doing so may compromise your experience with the TRX7 CS Pro and, in some cases, result in loss of your account data.
You have two primary options to charge your TRX7 in your vehicle:
1. Connect the TRX7 CS Pro to the Vehicle Power Adapter (VPA) or Cigarette Lighter Adapter provided with your TRX7 CS Pro via the micro-USB type cable.
2. Connect the TRX7 CS Pro to the charging cradle > connect the charging cradle to the VPA > plug the VPA into your vehicle's power outlet or cigarette lighter source.
Note: Using other Vehicle Power Adapter or cigarette lighter adapter will not charge the device. It is recommended to use the VPA that was included on the purchased.
