Attachment 29279
The cable is fairly long but I'm not sure if it is enough to route behind all the way to the glovebox. I haven't really thought it through on how to hide the wires. My initial plan was to build a USB Plug that was wired to a 12V switched source behind the ashtray and move the aux to the ashtray. I could then route the wire, behind the steering column and go behind the dash to the ashtray. This is not a well-thought plan yet as I haven't looked at the routing areas on how to go about doing this.
I also didn't look into 12V-5V stepdown transformers and USB setups.
One thing to note and I'll edit it, is the button is attached via 3M sticky tape. Kinda silly that it isn't a magnetic removable unit like the others ones I looked at, but it's fine for my car.
