Hi all. I have a LR322 05 plate Vogue. I rather stupidly tried to upgrade my BT module for one off an 09' Vogue. I plugged the unit straight into the quad lock, without realising the wires need reconfiguring. If I bypass the BT module by linking through the fibre optic cables - I can get the main screen to display the 'Land Rover' logo for 10-15 secs. Then it turns off.

Does anyone have any ideas where to go from here? Is my amp shagged?! It's the Harmon Kardon Logic7 btw.

Cheers
