How do you plug in a USB lead in a “rear USB in” car stereo?

I feel like this is a silly question but...

When a car stereo says it has a “rear USB in” does that mean you literally plug the USB cable in to the back of the stereo? If so how do you do that? Or how would you get it back out? Is there even any room for it when it’s in your car?How do you plug in a USB lead in a “rear USB in” car stereo?
Never seen it before, but you would want to get a USB extension lead, probably around 60cm long (estimate).



Then plug one end in the back of the car stereo, and feed it through to maybe the glove box, where it will just sit.



Then when you want to use a usb device, plug it into the end which is in the glove box.



A professional could think of a better place to put the extended USB besides the glove box, like perhaps in an empty switch button.



A simple, diy job, would be to put the end in the glove box.



Good luck.How do you plug in a USB lead in a “rear USB in” car stereo?
Ok In This Situation What The Installer Will Do Is Run A USB Extension Cable Into The Glove Box So It Is Accessible And Yet Concealed.How do you plug in a USB lead in a “rear USB in” car stereo?
if your car radio have 4 small wholes, one each corner of the front panel its easy.

those wholes are for removing the radio. any garage who fits radios could do this for you. after removing the radio just plug an USB extension lead (USB both ends male/female) and get it from the back of the radio into somewhere you can reach. Have the radio in place again and you have a USB connection available.

if you don't have the 4 wholes in the radio, you'll need to access the radio from the back either by removing the radio or trying to access from the bottom of the dashboard. (This is sometimes very tricky depending on the make and model of the car).
