I have a 2007 Megacab with factory Navigation i was wondering if anyone knows where or how to upgrade it or wether the cost is prohibitive and should just replace

To buy the nav cd you would need to update you're looking at spending ~$150 depending on where you shop from, I'm sure the dealership is more and they will also nail you for labor. I've heard some horror stories with people updating so I don't know how much your time is worth per say but I've also seen plenty of people claim its not that difficult.

You might be able to find a better deal on Amazon or eBay though.
