Just take your time, I have only done 3 installs in the last 10 years, but I just make sure I have all the tools and bits I will need before starting. Then just take it nice and easy. Stop for a break ( as I said, I drank lots of tea ! ) if you get stuck, and refect on a way forward.

If you give me some notice of when you are going to do it, I could check if its a day I would be around to keep an eye on the BBS, or be available via Yahoo/AIM etc.

Worse that can happen is you get the old head unit out and cannot install the new one, and that should save you some folding green stuff, should you need to pay to get the Empeg installed.
