I have no way of testing this unit, so I'm selling it as is. I can confirm that it powers up when plugged in using the AC adapter or the cigarette lighter adapter. It does not power up when using the removable battery, so I think that is no good anymore. A RAM yoke mount is included. Please look at the pictures carefully. If you don't see it in the pictures, assume it's not included. Feel free to ask questions and I'll do my best to answer them. Thank you.
