I had the same firmware and had it updated by vauxhall and i can attest to the fact that it will solve all your black screen android problems. Also with the later firmware you get independent sliders for radio, navigation and phone calls and the bug that sometimes make the preset buttons forget the ...

The headunit is called HMI. If you have navigation it will be navi 900 and if you have not it will be R4.0 ..... And if you have not even got a 7-8" touchscreen it will be the BT600 radio. No matter what unit you have, the HMI will have the rear output, but if it is disabled i do not know. There are...

Aha, yes, the TPMS sensors will probably only transmit the pressure if the wheels are turning, to save the battery. So the module probably just lost the last transmitted pressure and was unable to show anything before it got a new signal. I bought the relearn tool as i have both summer and winter ty...

The -- instead of pressure, could be because the TPMS sensor's are out of battery and needs to be replaced. More than one can go "bad" in a very short time. If they are from the same batch and have run for exactly the same amount of hours, the batteries might die at almost the same time. My suggesti...

It is very difficult to make these bulbs error free, as you would need to burn off the watt's that the LED bulb does not use. If the LED bulb only uses 15Watts and the original uses 55W, you need to burn the additional 40 Watts in a resistor. If you want to burn 40 Watts at 12 Volts you need a 3.6 o...

Astraowner Does the temporary disconnection of the battery have to be disconnected at the battery location in the boot or is there a more accessible location under the bonnet. I notice there is a negative cable bolted to the chassis near to the jumping points. Lucks The only place i know for sure w...

Maybe the low battery voltage when cranking has put the modules into a bad state, that prevents them from working good. I would try to charge the battery in the car fully, then disconnect the battery from the car for a few minutes, connect the battery, wait 5 minutes, and see if this solves the prob...

When adjusting the volume, there is a visual representation of the volume. Does this number increase as well ? I would have suggested the auto volume that increases the volume to compensate for road noise at higher speeds, but it seems you have this part sorted. Maybe the volume is only shown when u...

Agreed, it needs a lot more force than you would think to click into place.

Blue one, but really and good ground spot on the car will do.
