I've owned my E39 M5 for about 5 months now. I am only now starting to upgrade the HiFi. I want to purchase the Umno-Tech USB MP3 interface (www.umno-tech.com). I was asked if my current radio has DSP. I also purchased a used BM54 radio from year 2009 but haven't installed it yet. and here are the questions:
- why does it matter, when ordering the USB MP3 interface, if my radio has DSP or not? the interface for the non-DSP radios is much cheaper
- is DSP only an equalizer?
- will my BM54 radio which was produced in 2009 also have DSP?
- what is the difference between the BM24 and the BM54 and BM54 back?
I tried to search but didn#t find enough info to answer my qiestions
I appreciate your feedback
