Posting this for a friend as I do not think there is anything out there like he wants besides bluetooth but could easily be wrong. So I came here to seek an answer... Also I apologize if this belongs in wiring but it does have to do with headunits.
"So I am looking for something that just may not exist. Since the usb outlet on my headunit is on the front, not the back, i have to run a wire from the front around the back behind the dash to my glovebox for ipod interface. This = not clean looking. I was thinking how they make wireless usb mouses with the little nano receiver and thought I can get a similar thing except instead of having a mouse at the other end have a female usb port which i can plug the ipod into in the glovebox. Basically i want a wireless usb extension cord with a nano receiver. obviously battery powered or 12V at the least. Does such a thing exist? I have a wireless mouse with nano receiver, can I alter it to work. I searched the internet for a good hour and found nothing. "
Thanks for the help guys!
