Hello, friends!
I’d like to share a small discovery regarding my Volvo XC90 T5, 2019 model, imported from the USA.
Everyone — including the official Volvo dealer — claims that the VOC (Volvo On Call) system does not work on US-spec cars, because they use different frequencies/standards.
I installed the Volvo Cars app on my phone and connected the car — but none of the features worked:
• It only showed that the car was in the USA in 2023,
• Software version was 3.4.4,
• And a message appeared saying the VOC subscription needed to be renewed.
I asked the dealer: If I pay for the subscription, will VOC be activated?
The answer was: No, it won’t work, because the car is from the US and the modem operates on different frequencies.
But here’s what I did:
Yesterday, I changed the vehicle configuration parameter 191 TELEMATIC MODULE.
It was: 04 With Telematic module, USA/CND,
I changed it to: 0B With Telematic module, Russia LTE.
I made these changes hoping to activate the built-in modem in the car (I previously wrote about it here: https://www.drive2.ru/l/707854591919656102/).
And guess what?
In the evening, I received a notification from the Volvo Cars app:
“Car unlocked”.
I opened the app — and to my surprise, a lot more information appeared, which was not available before:
• Fuel level and estimated range,
• Door lock status (locked/unlocked),
• Driving statistics,
• Car location (though it still shows as if it’s in the USA).
My question is:
Is this behavior normal and does it work like this for everyone?
Or is it actually possible to activate VOC on US-import cars if you configure everything correctly?
Would it be worth paying for the subscription to unlock the full VOC functionality?
I’d really appreciate any insights or experiences you can share!
