Dashcams...Help!

[GeordieSPG]

Right, I'm getting myself tied in knots and looking for some advice from you all! I'd like one front and one rear.

I don't really care if it has a screen or not. I'm not sure of the value of GPS or WiFi...I'd like them to be mostly hidden and would hard wire. I'd also like some kind of parking mode, to catch any dodgy buggers who may "bump and run".

I've ended up with the following list:

Mobius - Small and cheap...no GPS (is it important)...how discreet?
BlackVue DR650GW-2CH
Transcend DrivePro 200 or 220
Street Guardian SG9665GC
Nextbase 512G

Any recommendations?

Thanks in advance
