FAQs
Q1: Does S8 Gen4 support both wired and wireless CarPlay / Android Auto? ---No. S8 Gen4 only supports Wireless CarPlay and Wireless Android Auto.
Q2: After connecting Wireless CarPlay / Android Auto, how can the head unit get internet?--Because Wi‑Fi is already used for Wireless CarPlay / Android Auto, it cannot connect to a Wi‑Fi hotspot at the same time. Please use USB tethering from your phone or insert a 4G SIM card into the head unit instead.
Q3: Can S8 Gen4 show front and rear cameras at the same time?--- No. It can switch between views, but it does not display or record front and rear cameras simultaneously. Note: This included camera AC-HD01LR is for live viewing only and does not support recording

It also features upgraded memory for smoother, faster performance.
Q6: Can I plug a Fire TV Stick (or HDMI cable) directly into this unit?---A6: No. The S8 Gen4 does not have a built‑in HDMI port. To use a Fire TV Stick or other HDMI device, you need the ATOTO AC‑HAV50 video adapter (sold separately).
