Just installed a dual USB charger. I simply replaced the mini plug port.
It has two 5V 4.2A USB ports and also shows the voltage. I am thinking to add one for the 2nd and 3rd row later.
We bought a 2012 Mazda 5 couple of months ago and decided to install an after market DVD navigation system plus an rear view camera. After researched online found this model (QL-MZD755/ROF-1407HD-2) is pretty decent.
Thanks to sigor2011's youtube video. The installation didn't take long.
Just...
