Aerpro APUSBGM2 Dual USB Charge & Sync has been designed specifically to suit various Holden & Isuzu vehicles (Vehicle housing may require modification in some models). It replaces the spare factory switch blanking plates in the vehicle dashboard that measure 22mm wide x 39mm high, providing seamless USB integration for your vehicle. Featuring two USB ports, one is designed for smartphone and device fast charging at 3A max and the other provides USB pass through sync for Audio, CarPlay & Android Auto when connected to the rear USB input on compatible aftermarket headunits. The USB ports are bidirectional, allowing the cable to be connected either way and the charge port illuminates blue making it easy to find day and night. The clip-in design combined with the simple 3 wire plus USB connection, makes it quick and easy to install, providing a professional and discreet USB upgrade solution for the vehicle.
