FAQ:

Q: Do I need this kit if I already have the GROM IPD3/4, USB2/3 or MST3/4 kit? 
A: The BTD is required if you want to use a smart phone as a hands free kit, connecting an iPhone or Android phone without the BTD will not allow the call through the car system and there is no external microphone. This kit is also required if you want to stream music wirelessly without a cable i.e. keep your phone in your pocket/handbag.

Q: Is there much difference between controlling music playing via Bluetooth AVRCP and a cable connection (iPhone cable or Android micro USB cable)?
A: Yes, the BTD gives basic control (track up/down). If you connect an iPhone using a cable or Android phone using a micro USB cable then you will have full control from the stereo/steering wheel buttons i.e. the disc buttons will let you change folders or playlists, repeat, scan and where available CD text. Your phone will also get charged.

Q: Is there a difference in sound quality between wirelessly streaming music and directly connected?
A: The GROM-BTD gives excellent sound quality, when in a moving vehicle it is difficult to distinguish between Bluetooth and cable methods.

Q: How many phones can be paired with this BTD?
A: 2 devices can be paired, with only one being active at a time.

Q: What is a GROM Audio Integration kit?
A: A CD changer emulator. A kit that connects into your car radios CDC or extension port and pretends to be factory fitted equipment.

Q: What limits does the BTD have?
A: The BTD is designed to work when in GROM mode (CD changer mode) only.
