The latest Techstream goes to V17 but many people prefer using v12 which allows various customize settings. V12 has been tested working great with vxdiag vcx nano Toyota interface.
If techstream v12 does not recognize vehicle (have to manually input) and does not allow to change any setting, check following:
Update vx manager to latest version on www.vxdiag.net
Update firmware
Update license
The main screen of VX Manager, where it can be updated and also refreshed the license.
Click on “Update License” and “Update Firmware”. Be careful to use USB connection during upgrade procedure.
