Okay, quick GPS app review:
I had a Garmin Nuvi 310. It was pretty good, easy to uses very handy features etc and got the job done. But the maps and SW only works with Garmin hardware, you pay for any map updates and the devices are expensive.
so when I bought my TyTn, I sold it and got handymap AI Gold. I bought a bluetooth GPS receiver cheap off ebay, and away we go. I was really impressed by it. It worked perfectly, and I did not miss the Nuvi at all. I quite liked the idea of not leaving an expensive GPS hanging from my windscreen to tempt all & sundry.
So this afternoon I checked out nav4all at
www.nav4all.com They claim to have FREE GPS nav software! I downloaded, got it hooked up and it actually works. It is free, so its rather basic, not nearly as nice as handymap. But it will definitely do the trick, and you don't really need the funky 3D nav of handymap, nav4all works just fine. The problems is that it does not work of a map installed on your device. It looks like it downloads the local area info from you phone internet connection as you go along. not cool
Finally, I got also tried the latest version of tomtom navigator today. OH MY WORD! this puts everything else to shame. Handymap does'nt even come close. It is beautifully optimised for PDA use. you set it up for left hand use, so you use your left hand whilst driving. All the buttons are big enough so you can use your left thumb to access any menu option whilst driving. The interface is so simple a child could use it. The 3D nav is stunning, and you can download about 20 different colour schemes for it.
And the navigation is great. While handymap always tried to take me in the most direct route to the nearest national road, this one guided my via provincial roads, much less traffic and higher speed limits.
And the celebrity voices thing rock! I am currently undecided between having John Cleese or Yoda guiding me.
So, hope that helps.
