My guess would be highly unlikely between brands, but I recently changed out my Pioneer am/fm cd unit for a new Pioneer am/fm cd unit with the aux port and the plugs matched making it a simple unplug the old and plug in the new. Jeff

Question for the vehicle audio buffs out there. Is the connector (plug) and
wiring for a stereo head unit (receiver/CD player, etc) standardized
between different brands? In other words, if I have a modern (last few
years) head unit made by Brand X will another head unit from Brand Y fit
without having to rewire the plug that connects everything to the back?
Just curious, question prompted by a couple of questions I've received.
