Redsteve you absolutely smashed it with this post. Ive been driving around with no stereo, satnav or temp controls for 2 months since the kids drained my battery by leaving the internal lights on. Didnt want to get ripped off by the dealership to get it done so searched on here. I just joined this club just so i could say thanks to you for this post, it sounds like youve saved a lot of people a lot of grief with this one. Well played.
