here are an estimated 30 million GPS receivers (GPSrs) currently in use in the civilian market. These receivers come in a variety of forms, from hand-held receivers, in-car systems, add-on devices for hand help computers and embedded receivers in other devices (such as watches and cell phones). The user manuals explain the basic functions of the GPS system, but they don't go into any detail about the finer points of the technology, and they don't tell users how to modify it, tweak it, and hack it in order to become power users and get the most out of a GPS system. These documents don't want to reveal how to take a GPS to new levels! Hacking GPS does that and more! It offers the following coverage that no other title on the market details:

·Hardware Hacks - Secret keycodes, hidden features, building power cords and cables, hacking the battery, hacking the antenna, mounting your GPS, protecting it from impact and falls, making a screen protector, and solar powering your GPS.

·Software Hacks - Hacking the firmware, hacking into your PC Connection with a GPS, and COM or USB

·Data Hacking - Software needs -free and commercial, creating data, waypoints, screenshots, troubleshooting, and more data tricks

·Playtime - GPS Games, Hacking Geocaching, and use your GPS as a Metal Detector

·Any potentially dangerous mod (from the point of view of the device) will be clearly labeled and precautions to take listed.

·How to get a deeper understanding of how receivers work and how to get more out of them than the manufacturers want the users to!

·Hardware that the reader can build to increase the function, performance or power of theirGPS.

Hacking GPS fills the void that the manuals leave by giving the GPS user the information they need in order to get the most out of their investment - by hacking the system and taking a look at all of the super cool tweaks that can be done to/with a GPS.
