Hi Lee, and welcome

I in the same boat (all aspects of your story!LOL!!) - looked at the waywell thing and I'm still not convinced. I'm after something with a bit more Ipod control, especially now I've got an iphone with TomTom.
I'm looking at the Pioneer 4100DVD - about the same price as the Waywell, but no satnav. Not quite as OEM-looking, but a better-sounding unit from the off.
Speakers, well, it's a minefield.
I'm going for some Focals (had them in my Scoob), nothing too mad. I've also got a 12" sub which will go in my wheelarch setup

In all fairness, the weak point isn't the OEM speakers, it's the rubbish Head Unit......
I'm going to change the unit first and see how it sounds....
