Hey guys!
I installed a nexus 7 + usb dac + amp in my e46 M3 and I've had to use a ground loop isolator to remove the horrible buzzing from the nexus 7 charging which has impacted the SQ
Heres a quick video of my install
I currently use one of these for the DAC : Behringer UCA202 U-Control Ultra low-latency 2 In/2 Out USB/Audio Interface: Amazon.co.uk: Musical Instruments
I've heard that others have been getting ground loop interference using this dac also for their installs and some have suggested upgrading to a FiiO E10K USB DAC and Headphone Amplifier as they've found that they don't get any ground loop noise from that DAC.
My question is: Is there a USB DAC for around similar money (£60 on amazon uk) that will not suffer from the ground loop issue AND has an amplified microphone input so I can use the hands free microphone that came with my sony ericsson handsfree kit (its just a typical microphone with a small headphone jack that is already wired into my car) I've tried plugging it into the behringer UCA202 but because the input on the behringer isn't amplified..my nexus 7 doesn't acknowledge there is a microphone input.
