      Notes: The locations of SW2 & SW3 are unidentified. To install an
      internal modem as either COM1 or COM2, the PAL chip at U65 must be
      replaced with a SER1 U58EC chip. Hyundai no longer stocks this chip
      and there is no third party sources known. The location of U65 is
      unidentified.
