Kept saying device already activated. won't connect Bluetooth. chat icon does nothing. found support number and called. said to text them. they actually responded within minutes and fixed my issue. edited my review. 4 stars because I can't use it on my other cars. either I don't know how to switch between cars or you have to buy one for each car.

Previously I was able to view full codes for my power steering system and SRS system. Now when scanned it recognizes there is a code but will not display the full code. Just that there is a SRS fault. It seems an app update has taken away the functionality of this code reader. The Ai slop chatbot is garbage as well. Don't waste your money on this glorified e-waste.
