Audax rides

Cool, just ordered an eTrex 20 from amazon. Need to get a handlebar mount now. And then learn to use the thing.

Try it out as much as you can before hand, i.e. on your commute, or leisure rides, etc.

Most importantly try it out in various sitations where things go wrong, i.e.

• Go off route intentionally, what does the unit do? Does it guide you back properly?
  
• Intentionally go off route but join up with the route a bit further on. Does it handle that?
  
• Plot a route that's a loop that shares the same roads for the first few km or so and then deviates, what happens when you get to that point, does it send you the right way?
  
• Turn the unit off half way through a route, then turn it back on. Can you get back to navigating along the route?
  
  

etc, etc.
