Hello. I have R53 and I'm using its original audio system plus this. It's working properly except one issue - there are some glitch noises when I turn the volume a little higher (especially for the songs with more bass). Thence I'm not really using its full capacity. I suppose it's because of the adapter from the link (there were no issues before buying it). Since I don't want to change the whole audio system (at least not now) - I was wondering if it's possible to change only the head unit (CD/Radio) with a new one that can play music from flash drives and won't use any adapters? Also, it is important for me to be able to use the wheel controls. Is all this possible?
