I will appreciate a discussion on this from riders who have used GPS or other means instead of the ACA maps.
I always in the belief that a GPS is a secondary navigational device beside a compass and a good map. Having my fair share of getting really lost with outdated maps and poor AI guidance and little to no cell receptionfor 3G or 4G in some parts of the country with my Garmin eTrex, I now use it sparingly. I also started carrying a Blackberry Playbook and have used the GPS and Googlemaps and Viewranger GPS software plus BikeGPS for all bike trails database. Again, I use that as a reference and not the source.
If you do decide to navigate with a GPS, always bring a map and small compass as your backup and learn basic navigational techniques. I mean you should know at least where the sun rises and sets! Sadly, I met a few individuals who relied heavily on GPS and did not know that!
Lastly, do not rely on your phone's GPS unit. While it is accurate enough for cities and most outlying areas, it is not as accurate as having a dedicated GPS unit like a Garmin nor does it work all the time in all terrain. In that case, I have a Dual Electronics XGPS 150 mated to my iPhone 3GS for this very specific task and with Mapster, I can have access to their maps database whenever I have access to a 3G signal. It's small. For backup battery, I have a Energizer external battery that can power the iPhone for like 16hrs + in full navigation and 3G mode. and it's not that heavy. The external battery works with my Playbook as well.
