I went a little higher class than the previous poster and went with the following in my thread:

Pro-Clip Mount between 20-40 depending on your car, if you don't want a windshield of vent held mount these are the best way to go imho. If you don't care then drop off that $40
Seidio Powered mount, $80 ish plus shipping depending on if you want a speaker or not. These mounts seem to be the best option if you want easy in and out for your axim as well as very few wires, arkon also has a mount but I have an x30 and it was not an option for me.
CF or SD Card, if you don't have a 1gb+ of one of these cards then you will have another 70 ish.
BT reciever $100... buygpsnow.com BT-339
Software... well thats up to you anywhere from $90 - $200 ish
I spent a week looking over all of this and then decided on what I wanted.
I suggest you do the same.
