Before you start

• Available services or connection methods will vary depending on the car stereo. Check the manual for the compatibility of your car stereo. 
  • XAV-AX3700 does not support Android Auto and only support Apple CarPlay

   Notes:

   • The condition of the cable you have been using may have deteriorated causing it not to work properly.
   • If you use an iPhone, we recommend using a Lightning cable manufactured by Apple.
   • For models with a supplied USB extension cable, if you need to use a USB extension cable, use the cable supplied with the car stereo.
