In car kits...

[Alex]

I was thinking of upgrading my phone to a K700i, and thought if there were any available deals then getting a car kit would be a really good idea. I want something that basically can charge your phone while on the move, mutes the stereo (not entirely necesary) and has a microphone and plays back through the cars speakers. Oh, and I'd much prefer a professionally installed one to those little ones that go in the cigarette lighter!

I looked at the carphone warehouse, and on offer it would be £170-£180 with fitting, which seemed quite steep to me. Does anyone know of anywhere cheaper, or, ideally, somewhere that would do it for a very low price as part of a new contract deal if I got a K700i at the same time?

EDIT: This is what I was looking at when I started thinking about it, with a £70 on top for installation...
