Does anyone make a bike GPS that reads Google Maps.

I have a Garmin 710 and it only sees the roads. I end up using my smart phone to find the best bike route via Google maps and then use the Garmin unit.

I have heard the the Edge 1000 has lots of bugs and thinking about just using my smart phone with a water proof case and extra battery. I am also hoping that the I Phone 6 will have better battery life so I would just use a water proof case.

For now I will charge my Garmin 710 every night since the batter is getting old and hope that someone will make a better bike GPS.
