Was wondering if anyone has yet tried using their Nexus 5 as a dash cam using some of the popular apps out there. Specifically wondering if you have used it as a dash cam while using it to play music and use Google Maps Navigation at the same time. Has anyone tried this? Do you guys think it is fast enough? Seems a pain to fumble with two devices, but would a separate phone, or dedicated dash cam device work better? Any recommended docks for this? What apps did you use? What car did you mount it on? Got any videos?
