and Here:

I was thinking about the Sedio car kit, but I like the idea of having separate volume up and down buttons and on/off switch that is present on the mr. Handsfree kit. I plan to use the 'quick and dirty' cigarette lighter method until I have time and money to do a proper install. My car is a Mazda Miata ('99).

Does this carkit need a BT patch? I don't see it anywhere on the P1 site:

or the thread:

That said, are there any other carkits (doesn't have to be bluetooth) that I missed (besides ThB, which I believe isn't out yet) for the same price or less?
