Satnav dashcam

Ive tried the search function on here but cant find much i was wondering if anyone has any experience of the satnavs with built in dash cam
Do they actually work or does the dashcam slow down everything
Do they get a clear picture
Am i better of with 2 seperate devices which i wpuld rather avoid
Thanks

I’ve got a Snooper satnav with built in dash cam.

Works fine.

I have a Garmin one, quite big at 7" (oooeerrr missus). It’s fine, not slow and has a lot of good features like voice control.

I’ve got the Garmin dezlcam and it’s been brilliant

Thanks does the garmin let you drop a pin as a destination
Has anyone used aguri or trucknav aswell
I want a 7in screen so i can properly look at the map as was really struggling with my old garmin today
