Well, I got it 2 years ago...it is working fine, no issues so far at all, but I want something new and something that has sat radio and hd radio. I think the radio reception is not the best of that unit as well and the sound is not the best as well in my opinion. I don't have DSP as well and did not have a sub either. The sound was somewhat terrible. I added a sub and amp from BSW and sound was way better but still worse than my other car factory radio, which drives me nuts. So, yes you can add sub and get signal from rear woofers in the trunk where the factory amp is.
I just want something new more powerful with more functions and options and something that makes great sound inside the X.
I will probably sell my unit for 200 dollars, once I found a good replacement
