I have my aux cable mounted in the sunglasses compartment. Personally, it drives me nuts because I have to wrestle with the wire to all get into the compartment when I want to disconnect and tuck it all in so I could close the door. It's pretty troublesome.
If I was the one to install it (PO did it), I would have gotten the euro tray and snaked it through there.
If all goes well and the Dension setup gets installed, I plan on getting the euro tray and putting the iPod in there. Otherwise, I'll buy a spec.dock and use that instead, though they're really expensive...
Keith,
For the euro tray, BavAuto has it cheaper by about $10 after shipping. Their price shipped to my door is $42.90, while ECS has it shipped for $51.23.
