It’s not possible to use the snap in wiring for any other purpose.. the ULF is coded to only provide phone support on this unit
Others have tried and failed
Not strictly true, if removed then the 12v positive and negative can be used to power something like a USB socket for phone charging etc (you'd have to use a step-down transformer**, which a readily available). The wires are .75 and fed directly from fuse 13 which is a 10amp fuse, so no problems here.
Also there are two types of Snap-In cradle (Eject Box), there's the standard Eject box, which just has power and antenna for charging the phone and boosting the signal. And there's the MEDIA Eject Box, which has the addition of a data/media connection to either the MULF (via the USB Hub) or directly to a Combox. I think this is what you are referring to in that most posts on forums say it can't be used for anything else, although I've read where someone has got it working but never said how, so I'm still investigating this at the moment.
**Step down transformer...
