Nokia hands free options

With the recent law change in NZ requiring hands free operation of mobile phones while driving, a lot of people are looking at ways to comply. In theory it should be possible to avoid having to buy a hands free kit. All you would need are a cheap cradle and the following phone settings:

Loudspeaker
Answer after x seconds
Any key reject
(Large Caller Info Display and Voice dialling would be a nice to have)

But can you set this up as a profile on a bog standard Nokia? No chance. Why? My assumption is that Nokia wants to sell lots of car kits. Grrrrrrrrr.

You can download third party apps that will set up a car profile for you. However these are not cheap in NZ currency. Does anybody have the spare time to make a free or cheap version?
