is it possible to split the live wire feeding my car stereo into 3 feeds so one is my stereo , two is my satnav power cable and the 3rd is my reversing sensor display. will this overload the wires? any advice how i can do this would be most helpful. thanks
I'm assuming you mean the wire providing the 12-volt power to your radio? And you want to connect other unit's it? It all depends on how much current is drawn by the additional units. Do they have fuses? What sizes are they? Backup cameras usually draw very little current and have really thin wires. Shouldn't be a problem. What type of navigation device? Does it use a DVD-ROM or is it just on a chip, like a portable Tom Tom, Garvin, etc.? If neither of the units' fuses exceed 5 amps, I'd say you're safe (in most cars) running it from the radio's power wire. However, you didn't state the type of car. Late-model GM cars or Audi/Volkswagen have low-current radio wires that use computers. They are known as data bus or can bus systems. I'd avoid connecting to these.
