I know some of you have an aftermarket Head Unit with Bluetooth. Some of these radios come with an external mike. I have a Kenwood unit with a mike. For the life of me I do not know how or where to run the wire. I have the HU out and am ready to run the wire and locate the mike either on the steering column, visor, pilar, etc. But where do you begin to run the mike wire from the back of the HU and out to these other parts of the car.

I simply cannot locate a path. For those who have run the wire could you please chart out a path for me and tell me how to access the path

Thanks
