hey everyone, I have just had an after market stereo installed. The bloke ran a new power lead as he said the bus was different, connected into the fuse box, the old stereo worked when the key was put in but now the ignition has to be on, is there an accessory line to plug this new line into or does that only work for the original stereo bus?

the car is a 2007 Octavia.
thanks.
Hans.
