Thanks for this comment... I have an android now and I was considering a cheap cateye for a dashboard. My wife has one and it works well for her.

I ran my phone exactly once as a dashboard (using Runkeeper) and it nukes your battery to have it always on. If it's not always on, then you might as well stuff it in a jersey pocket. Plus the bar mounts are not awesome and you can knock it off with your knee, a huge bump, etc.

I don't need directions because I never wonder, and if I did I would just look on my phone. This thread helped me decide to save up for a Garmin 500.
