Gots to post this for increased notice -- I have an EOnon radio (DVD/GPS/TV etc.) going into my 2012 Smart.
I have the Metra 99-8720b fascia plate, as well as plug and antenna plug.
While the Smart Power and Speaker plugs all actually match up correctly with the Smart plugs, the wiring is a little off.
Previous post by a forum member regarding the wiring schematic of the plugs of a 2012 Smart are not exactly what is in mine -- and the wires from the Eonon do not equate with the Smart wires.

For instance, the Eonon has wires for: 1) gps 2) bACK UP CAMERA 3) mUTE 4) mEMORY 5) POWER ANTENNA 6) empty 7) Ignition Key 8) Ground;
Whereas the Smart wires are for: 1) Unknown 2) empty 3) empty 4) Constant 12v+bATTERY 5) amp power 6) Dimmer 7) 12V+Ignition 8) Ground

I tried it all regardless of wiring, and the radio would turn on, the face lit up and showed stations, but no sound, and within 20 seconds, the unit turned itself off.
I removed the mute line, the back up camera, the power antenna -- no change.

What do I need to do to get sound?
Why is the unit turning off within 20 seconds -- tried it repeatedly.

Thanks for any help.

Sounds like there's an amp you need to bypass, but I'm not sure how. (See if Crutchfield has something to interface to give you a clue.). Try tying the ignition 7 to 4 constant to see if it will stay on. Otherwise I suspect that sitting there all these years your unit may have gone bad.

Thanks for the input.
1) I'll check Crutchfield;
2) Good idea. Will connect #7 with 4 (constant) to see if it will stay on.

FUnny thing, I also tried a second Eonon I happened to have (also from bygone project) and it stayed on, however, I have no sound (like the first Eonon unit I tried). The 2nd Eonon unit had different wiring scheme from the first one.
