I bought this one and it works. I haven't used it much, and I don't know how HQ it is, but it did work, it is Wifi. I haven't used it since the first week after I realized it conflicted with CarPlay.Thanks for the information! I have an old hard-wired OBD scanner and need to upgrade. I assume you are referring to the Car Scanner ELM OBD 2 app? Which specific (high quality) OBD2 adapter would you recommend? I use an iPhone.
I had an older Bluetooth version and I put it in the truck, but honestly haven't opened CarScanner since then.
