Anybody know what this is ?

Need a band expander (I have one installed in my car with factory head unit).

When I got my car it had a Disc changer in the trunk and a Tv in the dash lol. It was all Japanese but I still got local channels through the tv tuner... It was really quite a mess of wires once I got it all out!

I didn't get the factory stereo with it , it came with an aftermarket but then i had to change that too since it only played up to 89.9FM

I'm certain there was a CD or MD changer in your trunk at one time before you got your car. When I got my car there was no radio in it but I can tell it had a DVD player before because the TV antennas were still on the front windshield and the backup camera was still attached to the rear bumper. Technology advance so fast now you are better off with a new head unit. My buddy at work was thinking of getting one of those hard drive storage unit and that was what 5, 6 years ago? Now all you need is USB in head unit and a USB portable device, so much for a changer.
