Clarion NX706 2-DIN DVD Multimedia Station (2016) price has been contested on Amazon, initially offered for $429 which is dealer cost, them fixed at $699. Price still drops to dealer cost too someone reported it. 15 band EQ, TA, high and low pass filters plus digital optical out. There is usually one listed under warehouse deals near dealer cost as open box currently $452. If you follow the search the price will occasionally drop briefly. Just released in July is the NX807, $666.66 2-4 week ship.
Alternatively if you want true full DSP you can purchase virtually any double din and get a Minidsp CDSP 6x8 for $299, add a dedicated true measurement microphone UMIK for $75, they both sell direct from Hong Kong. Under the hood these DSP's offer unlimited options, as good as or better than Helix, programmable controller with 4 presets which can also control only channels 7 & 8 (bass knob), in addition to channels 1-6. Active 3 way front stage plus sub? You bet. Integration with REW (best free room analysis software out there) including 5 bands of PEQ per input and output, REW can generate PEQ's for direct import into MiniDSP as well. This option is very tempting if considering an Android head unit that supports Torque OBDII allowing you to view vehicle diagnostics on screen and integrate with factory steering wheel controls and other OEM functions. XDA Developers is a great resource for Android platform double din info including custom ROM's.
I complete in SQ, still use the Pioneer DEH80PRS as it has independent right left EQ, TA, and Auto-tune, however I'm using the Minidsp6x8 for TA & PEQ, 80 PRS for fine tuning while driving.
