I fitted my Alpine headunit no
problem.
I put the wires up out the way at the top left hand side, and left only two wires in the way. The wiring loom for the radio and the aeriel antenna.
After that the headunit slides in no
problem... I'll can easily pull the wires back down from the back of the dashboard if needs be.
Removing the top half of the glovebox helps too... most aftermarket headunits will come with their own wiring loom so hiring all the wires up out the way in the dashboard saves space and causes less of a hassle.
