Does anyone know how to determinewhether getting an updated Alpine navigation data DVD is worth the price? I have a factory-installed system in my 2005 T&C from Alpine, model RBS1, and many of the streets in my region are not included. Before forking over $200 more or less for a new disk, I'd like some info about what has been updated in my area.

How does one get in touch with these people?

 

thats hard to say dont even know what is updated some times. U should get one free update with the new system. There should be a booklet that came with the van and a 1800 number on it to call for an update.
