I was thinking about getting a dash cam and have narrowed it down to Garmin 55 and Nextbase 512wg. I would like to know your opinions. I'm more inclined for garmin as it's smaller and looks nicer. Otherwise the specs are identical. What I like about the nextbase is possibly being able to plug in a rear facing camera in the future. I just don't know how much vision will they obstruct. Can they be fully hidden behind the mirror? If you have a dash cam can you please post a pic of how you attached it. I see that Halfords can hardwire them for £30. The website doesn't specify if they can do it in A4. Has anyone got it hardwired by them.
