Very decent navigator

A tool should match the task at hand. If you just need to get from point A to point B avoiding congestions and there is a cell signal, nothing beats Google Maps. However, if you are a motorcycle rider who planned a 3,500 mile multi-day trip on a computer, saved it to a file and just need your GPS to tell you when to turn, and you are riding somewhere in the mountains without a reliable cell signal, Sygic is great.
Ive been using a Tomtom GPS for the last 10 years. The first time I opened Sygic app, I felt right at home. However, if you want to do the latter, you will need an Android phone. iPhone doesnt allow you to drop a file with the route into a Sygic directory.
Also, since the app runs on a phone, you have much better alternatives for audio. Car GPS dont support A2DP profile. In other words you can not hear voice instructions when you wear a helmet, unless of course you are willing to spend $700 on a Zumo. But you can pair a phone with any wireless airbuds and enjoy turn by turn instructions while riding.
