hello, i bought a clarion nx702 and installed it in a FRS, i cannot get the sound right on it, all of my speakers are stock, but i'm use to trebble and bass.....this doesn't have those options, it has LPF and HPF, what should i set it to? i understand you're an expert in this brand so if you can help i'd really appreciate it, also do you think they are going to patch the bluetooth with iOS6 (iPhone) so that you can stream music again? and is this in your opinion the best unit (gps nav/audio quality) unit or would you have went with something else?
