    This radio (I have HD radio option) has worst reception of any radio I have ever owned. Might be a problem with installation, but scanning on AM band picks up ZERO stations.

  • 0

    Dial control is badly placed -- when turning dial (for example to select music) because the dial is on the left, your hand obstructs your view of the display.

  • 0

    No illumination of functions such as album +/-

  • -1

    Poor layout of buttons and controls

  • -1

    Bad assignment of functions to buttons. About the only single-purpose button is the one least used -- the Bluetooth pairing.

  • -1

    Difficult to tune -- can't use dial control and the >>/<< buttons are difficult to use for manual dial (not scan).

  • -1

    Inserting a USB flash drive causes the system to switch from radio (HD) mode to USB, which is then silent while it reads the drive. Why can't it read the drive and play the radio at the same time?

  • -2

    Where's the "ON" button? Not marked anywhere on the radio.

Ian Jamieson: #sony_mex_bt3700u It is so annoying that the USB is limited to 4-5gb. I have 14gb memory stick, most of which is redundant because of the limitations of the head unit! Mar 24, 10
