If you can’t see your depot or vehicle in the booking process, there are a few possible reasons.
The depot might not appear if it doesn’t have an object linked to it, or if you don’t have access to that depot you are looking for.
If you can see the depot but not the vehicle in it, the vehicle may not be added to that depot or enabled for Carsharing, or it may already be booked for the selected time. Additionally, if the vehicle isn’t in the object linked to the depot, it will not appear as available for booking.
