Took this POS to a professional audio/tint place. Tech who installed it has the 700 series model. He advised me that the 128G storage card was missing. He also mentioned that of all of the installs that he as done with BlackVue dashcams, they never arrived in a brown box that was generic. He questioned if this was a refurbished unit. I paid them $125 to install a defective unit that cost over $500. So pissed right now. Thinking about cancelling my Walmart account.that pissed off!Update: Walmart shipped me a replacement. Took it to the same installer. He swapped out the front camera and, bingo, wifi connected. They also included the 128GB microSD card this time.Because I had to go thru all of that to get a working specimen, I'll upgrade the rating from 1 star to 3 stars. Good dashcam, just a roll of the dice.
