Type a chassis number. Get the head unit, every map it accepts, and the code. Automatic. No waiting.
The code is entered once on the head unit. It does not expire.
Fully automatic. Nothing is queued. Nobody checks your request by hand.
Type the 17-character VIN. You get the model, year, chassis code and the head unit fitted at the factory.
Only regions and versions that head unit accepts are shown. Nothing invalid is offered.
On screen and by email, kept in your history. Credits are spent only when a code is made.
