Happy New Year peeps. I picked up my 62 plate berlingo van 1.6 hdi 625 enterprise on christmas eve after breaking my transit up in cumbrian floods, and i must say i really like it. It has 41k and i got it from citroen blackpool. I would like to wire in my sub with inbuilt amp but i dont want to lose the bluetooth and sat nav functions in van (its a loaded berlingo all extras bar alloys). Can this be done? tia
