I bought one on these a few days ago. Installed it this evening while mrs was occupied!
The picture / video quality really is stunning I must say!
I hard wired it to the dome light, cutting the cigar lead it came with, which specifically said do not cut or serious injury will happen/fire danger/electroshock!! lol.
The iPhone app isn't the best! Noticed a spelling mistake in the setting page haha.
Finding the live feed option was a pain in the rear for me too, but eventually found it having asked the guy I bought it from (advanced-incar).
Very over priced bit of kit if you ask me. I paid 280£ and wish I waited for a price drop.
Having said that though, I can't stop playing with the dam thing now and love it to bits!
The voice is irritating (which you can disable, I think) and the sd card I replaced with a Sandisk 32gb. Doing this seemed to speed up video access considerably!. Both are class 10 cards, but the Sandisk ultra won hands down! So recommend replacing the pitta soft card they give you if you noticed stutter/slow playback.
thought I would chime in and comment about this dash cam any how. Hope it helps.
All the best,
Chris.
