Agreed. I just found this one on the Halfords website, Garmin DriveAssist 50 LMT-D EU 5" Sat Nav with UK, Ireland & Full Europe Maps and Built-in Dash Cam

A bit heavy at £280 but I'm going to go and have a look anyway...

I can get these for £180 - includes a 32GB SD Card:

Very good dash cams, from one of the largest makers of dashcams.
I have 6 of them in my family.
The previous version, LS460 was very very similar to the NextBase 512G
