That sounds very similar to what I did, but you might want to give my routine a try for what its worth. This procedure worked for me on my 2005 Toyota Prius Navigation system to transfer entire groups of contacts to the car. I had to use Astro File Manager and the native Bluetooth in the phone because the Bluetooth File Transfer app has never worked on my Sprint Hero.
I too exported all of the contacts I wanted to transfer to a .vcf file. I used Google GMail on the web which allowed me to export any group of contacts in my Gmail to a .vcf file which I copied to my SDCard. I had to edit the .vcf file since my car's system doesn't like multiple numbers per contact, so I had to split-up any contact with multiple numbers and give each a unique name manually, but this is just a limitation of my car's system to receive contacts.
Then, I installed Astro File Manager from the Android market.
Opened Astro File Manager and hit MENU/More/Preferences and selected 'Edit File Extensions'.
Selected the 'New Extension' button.
Input 'vcf' (without quotes) as the Extension Name.
Input 'text' (without quotes) as the Mime Type.
Input 'x-vcalendar' (without quotes) as the SubType.
And hit Save.
Now, I backed out until I got to my SDCard file listings in Astro, I Long-Pressed the .vcf file on my SDCard, I hit 'Send', then hit 'Bluetooth', at which point I then put my car in contact transferring receive mode, and I finally selected my Handsfree car system on the phone which transfered the .vcf file with all the contacts to my car.
