It should work on the Jetta, though it was made for earlier VAG models. On the Toyota, it is probably incompatible. Unfortunately the manufacturer provides no service or upgrades.

The power is supplied through the plug in the dash. It will not power on unless it is plugged in and the ignition key is ON in the vehicle. It took significant force to plug the cable in all the way. I have used this in an '04 Jetta and an "04 Audi A4 with no issues.

If you mean the scanner, it is powered from your car battery when you plug it into the OBD port. If it is not turning on, it is not getting power from the port or it has failed. You can try it on another car to see which.

Check that the "power" light comes on when it's plugged into your OBDII port. If not you may have a wiring issue with the car itself. I've seen this on more than one GM vehicle. Otherwise, if the power light does come on when it is plugged in, you might try using a different app to communicate with the unit.

Try a full reboot. The car then has to be "recognized" those step(s) vary. You may need to try a few things.

Dale, does the unit itself not turn on or just no function to the head unit?

Try moving the switch in the back several times. Check and make sure that the fluid jar is snapped in the unit all the way. If the unit is still warm it should be still working. Make sure you have power at the plug. The only other thing you can do is contact the company an see if you can get a replacement.

Sorry I can't help. My car does not work at all. I am waiting for the promised replacement. Good luck.

what kind of power did you supply, it has to be a direct power source eg. you can hook it to the cigarette lighter terminals if it still does not respond try the battery terminal and change the channel , do not connect it to a cigarette lighter plug, it will not work because it need a high power source good luck

Best bet, send it back and ask for a new one. Mine has worked fine since day one. You deserve for yours to work also. Hope this helps bro.

Did you plug the unit in? Mine works fine. Perhaps you should contact the a Seller for a new one.

Make sure the hood is on correctly. If its not on correctly at all, it won't work.

I had the same problem, couldn't get it to work from my Jeep's cigarette lighter. Finally cut the connector off and soldered on some alligator clips, and clip it right to the battery. That works.

try unplugging the cables and make sure no dirt/debris are in the connection points, once you get it all back together have someone look at the light while you apply the brakes and put the turn signal on. if that still doesn't work then there is a problem with that particular light and i would try to exchange it. hope this helps!!

Have you replaced the battery? The battery was dead on the fob I bought through Amazon.
