They can be used, but the software adaptation needs to be upgraded to a new version. The specific details are as follows:
If you have a second-generation SU7 and purchased the new fragrance diffuser set (Document Edition), you can use all functions directly;
If you have a second-generation SU7 but are using the old fragrance diffuser, you need to upgrade the fragrance diffuser to the latest firmware version (version number 0092). Only after the upgrade can it recognize the new Document Edition fragrance sticks. The new firmware version will be fully rolled out in early April;
If you have a first-generation SU7/SU7 Ultra/YU7 but purchased the new fragrance diffuser set (Document Edition), it can emit fragrance normally, but the in-car system functions (such as card page quick operations, super tasks, fragrance insertion reminders, etc.) need to wait for a subsequent in-car system1 version OTA to be used normally;
If you have a first-generation SU7/SU7 Ultra/YU7 and are using the old fragrance diffuser, two steps are required. First, you need to upgrade the fragrance diffuser to the latest firmware version (version number 0092). Only after the upgrade can it recognize the new Document Edition fragrance sticks. The new firmware version will be fully rolled out in early April. Second, the in-car system functions (such as card page quick operations, super tasks, fragrance insertion reminder pop-ups, etc.) need to wait for a subsequent in-car system version OTA to be used normally.
