Opel Onstar

Opel and Vauxhall Onstar cheap alternative and replacement

Did you, like me, also buy an (electric) Opel / Vauxhall in 2020 or earlier with Onstar? Then you have certainly already noticed that the advanced Onstar system no longer works at all. This is all due to the sale of Opel / Vauxhall by GM to Stellantis. Vauxhall Connect cannot be installed on older models and you cannot convert Onstar to Connect.

I was tired of endlessly waiting for Onstar compensation or paid alternatives that just don’t seem to come. So, I creatively replaced all deactivated components of Onstar myself. Discover how I installed a working eCall SOS service. But also how to follow the live car location and monitor the charge of my car.

Replacing eCall with SOS function in the event of an accident

Nextbase 622GW Dash Cam

One of the most important Opel safety features from Onstar was always the automatic eCall and SOS function. The car then automatically detects a collision and then calls the emergency services. Fully automated, independently if you do not respond in time. To replace this I purchased a dashcam of the brand Nextbase type 622GW with a built-in SOS eCall system.

This dashcam has a built-in SOS eCall function and does exactly what Vauxhall Onstar used to do. Namely independently detect collisions. And call in the emergency services with your exact location and share your medical data. The Nextbase 622GW is currently the most premium model and films 4K. The SOS feature is also available on cheaper models such as the 522GW, 422GW and the 322GW.

Thanks to my dashcam, I not only benefit from a reliable SOS function again. I also have received automatic parking monitoring for my car!

Replacement for GPS tracking function for theft protection

Samsung Galaxy SmartTag +

Another reason why it’s so annoying that Onstar stops working is the integrated location and tracking function via GPS. As a result, you can always find your way back to your car. That’s great if you no longer know where you parked it. You can also request the exact location and follow the car in case of theft.

To get this feature back I purchased a Samsung Galaxy SmartTag+. All Thanks to ultra wideband and Bluetooth and the worldwide Samsung Galaxy smartphone network. The exact location can easily be read live via the SmartThings app. It works great and a SmartTag is easy to hide in your car. Make sure you buy a “+” SmartTag and not the normal one, otherwise it will not work properly. Do you work with Apple instead of Android? Then the Apple AirTag is also a suitable solution.

Remote activate & follow your car’s charging status at home


With your car key and the IOS / Android app from MyChevrolet you can still start the air conditioning. You may check tire pressure and read your battery status within Bluetooth range. But because Onstar has stopped, you can no longer start a remote charging session at home. And no longer see how much you have already charged. I do not have an expensive charging station at home. And I prefer to charge slowly at the household plug. That’s why I bought a smart plug. I purchased a Fritz! smart plug with extra thick extension cord for my parking space.

Fully integrated with my home network, I can use the Fritz! Read the app everywhere, how much my car has already charged and I can start or pause charging. In addition, it measures the temperature of the plug and keeps track of all statistics. Don’t have a Fritz! Box WIFI router? Then take, for example another quality brand like a Brennenstuhl smart plug with a free app and similar function.

Make sure you check carefully whether the plug can be used constantly and safely at 10A. This is the case with both the Fritz! if the Brennenstuhl plug is the case.
