you won't be able to access any of that if you don't have the e-brake on. Those functions are locked out while driving. I have that unit. BTW, it's an iPC-106. It should say ECLIPSE on the screen of the iPod and OK to disconnect. if it doesn't there is an issue. Make sure that the A and B switches are in the right position, I can't remember where they should be but call Eclipse Tech Support and talk to Steve or Dale. They will be able to walk you through it.
There is little chance that the unit is bad. Those are pretty highly controlled units, still made in Japan.
