Do not buy from Seicane.
Do not buy from Seicane. If anything goes wrong, you are not getting any help or refunds, and then you have to find another system. I got their 10" system for Jeep, which broke after 5 months of use, and when contacting Seicane to get help, the help was to pay for a new motherboard and replace it myself, Nu refund or any guarantee was possible.
