Please Note: I AM NOT LOOKING FOR AN ALTERNATIVE SOLUTION

I lost track of this effort years ago but have need to geocode thousands of addresses nightly. I must use the very accurate database sitting on the machine, installed when the Nuvi map update installed Mapsource.

When I contacted Garmin years ago, they expressed an interest in providing an API for this, but then I heard nothing and did not follow up. Their database is provided by navtec? I believe. Anyone have experience with that format?

I posted on the Garmin Developer forum a while ago, but its a little lethargic over there :)

Has anyone done this? Does anyone know how it might be done without an API; meaning database structure and calls?

I'll take a solution in any language.

Added:

Garmin has expressed an interest in making this available to me. They just have not done it.

I do not know the database format.

I am NOT looking for an online solution or any other "alternative". This question is very specific.

I offered a 400 pt bounty for this. Jeff Atwood then offered 400pts also. If you would like to see a solution to this, vote up the question and I will chase up Garmin and show there is interest in finally providing this.
