How many minutes of video will a 32 GB card record in this unit?

For 3 minutes 1080p video, it will take about 300MB space, 32GB card can take about 320 minutes video which equals to 5.3 hours.

Can you set the camer up to record more than a 3 minute loop? can it just record until the chip is full then start over?

I have the Rexing V1-4K Ultra HD camera. On *MY* camera the available "Loop Recording" options are 1, 2 or 3 minutes, which I did not care for. However I did discover, quite by accident, if you set the video "Loop Recording" feature to "OFF" then it will default to loop recording 15 minute segments. For me this is a lot better than the 1, 2 or 3 minute options available on my camera. Hope this helps.

When I want to save a loop to download later is it fairly simple to do so while driving? The one I have now is too complicated!

While the DVR is recording video, press the button to lock/protect thevideo clip into a separate folder in the memory card. A key shaped icon will bedisplayed on the top right side of LCD indicating the video file is locked. Thelocked files will not be overwritten even when the MicroSD card becomes full.http://www.rexingusa.com/Downloads/Rexing%20V1-edited-Final-20150708.pdf

Does it have a microphone, and how good is the microphone if so?

It has a microphone and it picks up sound rather well and can be turned off if needed.
