great device

The following review is for BTD, which is a part of the bundle you are viewing.

my brother told me about this device, works as advertised and more...I have it installed on an '05 odyssey and use it for music and hands free phone.

BT Dongle works very well

The following review is for BTD, which is a part of the bundle you are viewing.

Anybody who works with BT on a regular basis knows that Apple i-devices can be somewhat finicky. This BT dongle, paired with one of the GROM interface boxes has no such problems. I have tested this with the iPhone4, 4s and 5. Works well, sounds GREAT. Audio quality can also sometimes be an issue streaming BT, but not with the GROM BTD.

easiest bluetooth to install

The following review is for BTD, which is a part of the bundle you are viewing.

This was plug and play. The entire setup plugs right into my factory stereo... Which Honda made difficult to replace. Now I have Bluetooth for safety and streaming music.

echoes

The following review is for BTD, which is a part of the bundle you are viewing.

overall, for music and audiobook listening, this is great, for calls, the microphone picks up the other persons voices, causing an echo. I have tried relocating the mic, and also wrapping the end of it, to "direct" it to only receive my voice waves, and i cannot get the echoes to stop.

Junk. Avoid this at all costs, because it doesn't work.

The following review is for BTD, which is a part of the bundle you are viewing.

The item works if you turn the key to the accessory position, but once you start the car, its cuts out, will not transmit any more sound into the radio, and will not recognize calls made on your phone, even though it shows that its still connected. Firmware updates from Grom didn't help it either, and it just leaves you with a large bundle of wires that get in the way. The microphone is also ridiculously large, and if mounted behind the steering wheel, it just gets in the way of the gauges. Do yourself a favor and just get the USB module and use an ipod or something, because this is just a frustrating mess with WAY too much wiring to deal with. I ended up cutting it out of the car because I didn't want to have to rip the dashboard apart to get it out, so returning it is out of the question as well.
