A:Answer Hi there. Thanks for your question. If you're asking if you should make an appointment for an Autotech installation, we do need to have an appointment, absolutely. It depends on the service. Some services can be as quick as 15 minutes where others make take up to four hours. The type of vehicle can also make a difference in the time frame. To get started, we'd recommend you connect with your local Best Buy's Autotech team. You can find information about your local store at www.bestbuy.com/storelocator.
