Think Twice Before Buying This
ThinkCar misadvertised functions this device doesn’t have for my car, lied that if I bought an Android it would allow me to access features that weren’t on my iPhone, tried to get me to subscribe to a paid feature that didn’t give me access to what I needed anyway, and gaslighted me to the point I had to escalate to PayPal to get a refund when I asked for a return. Tip: this device needs to talk to servers in mainland China to work so if you have a firewall like me, you may need to override it.
    I love it, we are using for our Mercedes sprinter all the time, works very good! Thank you

    Mis leading, you have to purchase add ons Even though it says certain functions included. Returned it because of that. I guess it’s fine for the price but yea misleading.
