GPS app for Android

[lenkf]

Looking for an Android compatible app that I can install in my device (Samsung tablet) that can accurately track distance and speed. I'd like to monitor speed/distance since the speedo on GZs are not known for accuracy. I've seen reports of GZ riders who claim to know with some certainty their exact mph and distance and miles per gallon, so I'd like to verify that with my GZ. Of course, such an app would be handy to also use in my other vehicles.

FYI, I recently ran out of gas while testing the limits of my '09 GZ with about 650 miles now. The trip meter had 165 miles. The reserve was adequate for another 20 miles and still had fuel at the bottom of the tank when I refilled.

Don't want to get off on a major non-GZ tangent or start a firestorm, just wondering what others are using. Such an app would also serve when traveling in my other vehicles. Needs to have ability to plot a map on the screen and audible would be a plus.

thanks.
