So I've had the Dice unit for about a year, and it's worked alright.
I decided I wanted to be able to use bluetooth audio, and started searching and found the Blackberry Gateway. Ordered it, it came today, I put it in.... and it only plays through one side (the right side). I tested the unit with some headphones and computer speakers so it isn't the Blackberry unit, I think.

Could it be the Dice then? How do I fix this?
When it's playing, the left side of the car makes a strange popping noise, along with some static, and if I play with the aux cord enough, it will play through the left side at an extremely low volume, albeit with the worst static I've ever heard in my life.

 

Bump

Also, could it possibly be that the power supply I'm using is too strong? The one that came with the Gateway is rated at 750mA, and the one in the car is 2 amps. Could that be causing the interference? Thinking about buying a cheapo charger online.
