Just watching Pat on TV and was advertising this unit, It has what the call Black Box technology,.
Could well be the "ultimate" DVR, and then some, better than most out there.

Read some online reviews (http://www.productreview.com.au/p/uniden-igo-cam-300.html), seems they don't like being bounced around on the tracks. This review is on the 300, but search for the other models and you'll find similar stories.

I’ve got a Uniden Igo 300 & yep the footage is vey poor quality compared to what else is available. As a result I wouldn’t consider buying a uniden dashcam again.
