Yeah, if the docking sled is installed in the car, you won't have a tuner connector when you bring the player into the house, so it'll be harder to get the serial log. You don't happen to have an extra docking sled in the house, do you?

Double check that you haven't set some kind of a setting in Hijack that disables the tuner module. It's got a lot of settings related to AC/DC detection and such (some of which will key off the tuner module ID number), but I don't recall if it's possible to bork the tuner module with one of them.

While you're mucking about with the sled, check for the following possible problems that might cause tuner module malfunction:

Miswired extension cable.

Loose docking connector pins.

Cut or otherwise incorrect sled harness wiring.

It's also possible the tuner module is just plain faulty. That has happened on occasion.
