I've only ever had original equipment, so can't comment on these retro-fits, but normally the Head units are VIN coded to the BSI. The BSI on later vehicles is secured, so required a valid account / server access to configure with Diagbox. ^ Mac ^ knows more about these retro-fits as he's done it.
Generally the process is:
- Buy car with NAC, connected services which were free for 3 years (later 2024 vehicle packages have different terms / offers)
- Dealer completes paperwork to authorise connected services for owner
- Owner creates their My Citroen / Peugeot / DS account and enters vehicle details and VIN
- Wait up to 2 weeks for system to become activated
- Activation is done and vehicle picks up authorisation OTA (over the air).
- Connected Services renewal option is offered towards expiration of free period.
- Failure to renew results in service being withdrawn
Personally - I never found Connected Services useful! A total waste of time and money in my own case - maybe as I live in a rural area, but:
Radar and Speed Camera locations never picked up a single one
Fuel stations prices were totally out of date
Even the Road speed signs for the maps were out of date (especially with the 20 MPH zones in Wales) that took nearly a year for them to update.
So I never renewed and instead, I now use Sygic via CarPlay - the 20 MPH zones were there within a week or 2, Speed limits beep all the time if exceeding the limit. Danger zones for radar traps work and so do fixed cameras. A much better system and I only pay £14.99 for the year for the Premium version. A no brainer, especially as map updates are very regular and much better.
