BT Dongle works very well
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.

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.

Getting Bluetooth and USB on a BMW 323i (E46 Chassis)
Purchased both the GROM Audio BMWSU3 along with the Bluetooth accessory dongle. Installation in the tight space behind the dash of the BMW 3 series is a bit of a challenge, patience and carefully following along with the many YouTube videos are a must. Once the GROM box and Bluetooth dongle were installed, along with the microphone for the phone, it worked great when I first started the car. However I could not get it to reconnect after restarting, I had to manually delete the Bluetooth entry on the phone and then reconnect to the GROM unit. After contacting GROM about the issue, they quickly determined that the unit needed a firmware update. Kudos to GROM for being so helpful, seeing as how I didn't buy the unit from them. After installing the firmware update through a USB stick, the unit works perfectly, even down to having the phone button on the steering wheel initiating a call. Sound quality on the microphone was excellent - the person I called couldn't tell I was calling handsfree over Bluetooth in the car.
