[QUOTE=Latitude65;10538782]OK, let me see if I have what you've said straight:

>The navigation function of the 705 isn't that useful.

>The mounting bracket for the 705 isn't really up to par. Plus, if I'm moving it from rental bike to rental bike as I travel I'd need to buy a supply of them.

>The 500 does everything one would want except for mapping. I would use the HR and Cadence functions as I've discovered over the winter that data is very useful to maintain my desired pace rather than using perceived exertion as I was doing.

Overall, y'all would prefer the 500.[/QUOTE]

The navigation function when used on the bike is useful, if one wants or needs it. I know my routes and look at other metrics. I download my data to mapping software in my computer and I use that feature after rides.

You only need one mounting bracket (maybe a spare) when transferring the bracket from rental bike to rental bike. The bracket is held on by tie wraps. You will need multiple tie wraps since you must cut the tie wrap to remove the bracket.
