Launch X431 V with Bluetooth/Wifi based on Android system, is a new car malfunction diagnostic device developed by Launch Tech for internet application.X-431 V completely substitutes X431 IV and X431 Diagun III. It passes on Launch advantages in car fault diagnostic technology, such as vast car model coverage, powerful test function, special function and accurate tast data, etc.
As we all know Launch x431 v pro ,V pro + is newest launch company products,it has software (or we can called APP) in main pad. V pro has most full system for almost all car till 2014.(Car list part 1,for your reference)
Uaually no need customer reinstall again,but sometime,during the ship time,the app has update,in this case,it will lead that when customer get unit,the APP is out of time,need update.Then problem comes.So many customer don’t know why X431 V PRO cannot update or no connection with car ,that because you need update your app first.
