rerouting aux input?

[scoobopdan]

So I think it would be cool for a number of reasons to have a dash cradle for my phone that could go directly in front of the driver (since the gauge cluster is centered). The only way I would do it, though, is if I could reroute the aux input up there. I was thinking one of two ways, the second of which I'd rather not do. 1) use a long stereo cable and run it under the plastic elements and exit somewhere by the driver's glove compartment. I don't like making irreversible changes, so I'm interested in what anyone could think of as to where the cable could exit. 2) go in to the wiring and directly reroute the aux input. I'd really rather not do this though.
