"Next year, GM's OnStar service goes dark in many pre-2004 models. Here's how to turn the old hardware into a navigation system

t's not really OnStar's fault that so many subscribers will soon be hitting the little blue button in vain. Starting in 2008, cellphone providers will stop supporting the old analog cellphone system, on which OnStar has long relied to provide near-ubiquitous coverage for its roadside-assistance service. That means all OnStar help calls must use the digital network. Problem is, some pre-2004 OnStar-equipped cars only have analog receivers and cannot be upgraded. But with a little hacking, stranded OnStar owners can still salvage some life from their orphaned system, no subscription required."

Here is another guide to tapping into your OnStar's GPS. It also has information on identifying the model number of the GPS board.
