plugged in my garmin gps unit and no power. pulled out the ash tray/lighter unit and there is no wire supplying power to the lighter receptacle. i see no wire at all coming in that could be connected. any information or insight as to why there would not be a power supply appreciated.

thanks

There's a contact on the left side of the ash tray unit that gets power from a receptacle with a plug in connector that remains in the console.

The cigarette lighter is not a standard plug per usual US specs. Your Garmin adapter won't work well, if at all. Most people buy an accessory US spec power port and hot wire it into the system (usually mounting it in the glove box).

I don't care for the smell of cloves...

It is a shitty set up, to be sure. There are contacts on the left side of the ashtray assembly that slide against each other. Sometimes they are worn, sometimes the springyness has gone out of the tangs.
Further, it is actually a cigar lighter and is a little oversized compared to modern day accessory plugs. Some get away by jamming a piece of cardboard in there to maintain contact, others use an step down adapter while others install a separate accessory plug adapter elsewhere...the glove box being a good spot.
