No — you do not need Wi-Fi to take photos during a vehicle photo session.
You can capture images as normal, even if you’re on the forecourt with limited or no internet connection.
Saving photos as a draft
At the end of a photo session, if you select Add More Photos and then tap the X in the bottom-left corner, your images will be saved as a draft.
This allows you to begin a new photo session for the next vehicle without losing any progress.
Uploading when you're back online
Once you’re back in the office with a Wi-Fi connection, simply return to the draft vehicle and tap the Upload icon (the middle icon on the left) to complete the upload.
