No very often it's mostly when they have something major coming up or need to promote something.
Job listing are often updated differently depending on the website that is listing the jobs. It is best to check the specific website regularly and get a feel for when they update the jobs.
you should update the drivers on your sanyo usb phone, or any electronic device for that matter, whenever there are updates on the website of the product.
Colleges typically update cost of attendance every year. You should be skeptical of any school that doesn't update it. You should be able to find COA (cost of attendance) on a college's financial aid page. Also, keep in mind that they are estimates, and the cost on your fall/spring bill may be different than the posted COA.
As a business how often should you update the W-9's on your vendors?
Norton does not often suggest you update your spam blocker. They only suggest you update it when you change firewall settings or update the software on your computer.
The creators of FarmVille often update the game. Unfortunately you can't.
I would look up the manufacturer's website for the audio driver you currently have to see if there is a update or patch you could download or purchase. This often saves you money and can save you from having to install brand new drivers.

With the official Tom Tom website you would be able to connect with the usb port anytime to update your GPS unit, however you are required to have an account. At least yearly would be probably be sufficient.
