Hacking GPS (ExtremeTech)

The information didn't mention that the book was out of date by a few years so most of the information was irrelevant to current gps units and TomTom is barely mentioned. Most of the information is heavily oriented to Garmin. * This is the "user manual" that didn't come with any of the 30 million GPS receivers currently in use, showing readers how to modify, tweak, and hack their GPS to take it to new levels!
* Crazy-cool modifications include exploiting secret keycodes, revealing hidden features, building power cords and cables, hacking the battery and antenna, protecting a GPS from impact and falls, making a screen protector, and solar-powering a GPS
* Potential power users will take the function and performance of their GPS to a whole new level by hacking into the firmware and hacking into a PC connection with a GPS
* Fear not! Any potentially dangerous mod (to the device) is clearly labeled, with precautions listed that should be taken
* Game time! Readers can check out GPS games, check into hacking geocaching, and even use a GPS as a metal detector "Your GPS is a really cool toy, but what if you could make it even cooler? What if you could build and hook up data cables, modify your iPAQ cradle to take a GPS connection, tweak the firmware, hook up to your PC without expensive software, use GPS data in a hundred creative ways, even solar-power your GPS? Suppose you could beef up your "first to find" quotient when geocaching, or use your GPS as a super-accurate clock. Well, you can. Read on - your adventure is just beginning!"--Jacket A guide to getting the most out of a GPS system provides information on such topics as building and hooking up data cables, modifying the iPAQ cradle, grabbing screenshots, and customizing GPS games. It's fun to uncover something that you aren't supposed to know about-many software applications and movies on DVD contain what are known as "easter eggs."
