How much could a stock navi sell for on here? for an 02-03.

 

Well you're going to have a very limited audience. It would be a wiring nightmare to try and put it into a non-stock navi car. Looks like your best bet would be to sell it to someone who needs to replace a malfunctioning stock navi. Or put it up on eBay. As for a price, I'm not sure. The market for them is so small.
