What to know before buying

Listing details to confirm

The listing gives two different vehicle-brand counts: 17 in its feature text and 18+ in its item highlight. Treat compatibility as unconfirmed for a specific vehicle and check supported models, software and subscriptions before purchase. The included-components list also repeats “Instructions for use” with a trailing colon variant, so the number of instruction documents is unclear.
