I found the information about subscription pricing at the following location. Scroll down and click on the relevant package near the bottom of the page.

You can look around for yourself to see what is offered. Follow this link for more information about the VIDA platform, which is provided by an independent company.

I read somewhere else that Volvo is targeting this at 3,000 dealers and 15,000 independents worldwide, so Volvo obviously recognizes that there is money to be made in selling subscriptions and parts (via dealers) to independents.

At only $50 for each diagnostic procedure, an independent could recover costs after servicing a couple of hundred P2 cars per year; a two bay garage couldn't do it, but a larger independent could.

Please note that each software download is extra cost; a part number is assigned to each download, and the VIN of the recipient car is recorded. The VIDA system will, at least in theory, know the software status of every car.
