Used Beat-Sonic QBF13 phone mount holder for a 2013 - 2016 Subaru BRZ or Scion FRS. Slides right onto the passenger dash trim for a super clean install. Check out the video Beat-Sonic has on Youtube for the QBF13 to see how it is installed. Easy 5 minute job. Most phone mounts will slide onto the T/L shaped part on it. Check out Beat-Sonic's QBA45 to see the type.
