Bests & Worsts Reviews from Amazon

I have a 2012 Hyundai Accent and their website said this product would work with my car--the website lied. I plugged it in and the blue light came on and started to blink. I tried to connect to it with my phone and tablet, neither worked. It could not read my vin number, then after entering it manually still would not connect. Their customer service was terrible and could only read off the instructions that I was sent in an email and came with the device. What was strange is that all the documentation said the device ID should begin with a CV, mine started with a CX. I tried many diagnostic things on my own, rebooting the phone, removing the device, reinstalling the app, moving to a different location, using wifi, using cell service. My service was fast enough, I measured 130Mbps from fast.com. I tried moving the phone and tablet to different locations, tried with the car running and just the key on. Tried their classic bluetooth mode. Tried a few other things too. Stay away from this product. I generally do not write such strong reviews, but this company really aggravated me. I was promised a reply by email from their tech support, then a phone call. No one from that company even followed up with me. I'm returning their product and I hope no one has the misfortune to deal with them or their product.
