fix some bugs

User reviews

Won’t work on newer cars

Bought the GM module and it only works on cars older than 2019. Total waste of money and it doesn’t tell you what’s supported until you buy a pack.

App issue

App issue can’t load the previous application

Not working AP200

Since last update I can no longer activate my tpms relearn. Smh bug fix yeah right

They broke the app.

“fix some bug” is what they said the update was. Yep, you fixed it alright. Locked my VCI box and made it a brick. No response from support at all. Shame on a company that randomly locks your device from being used for no reason at all.

Doesn’t connect via Bluetooth

The device does not connect via Bluetooth to the phone app. I want a refund. 😡
