Now JVC has introduced a new KW-HDR720 receiver which is the 'mid-range' model in their line-up of double-DIN radios. Both units are very similar and JVC has not made it easy to compare the detailed features of both units. So I have painstakingly reviewed both User Manuals and present my findings below.
older XR810 ($300 at Crutchfield)
- includes Bluetooth adapter
- supports HD Radio but not included
- parametric EQ has 3 bands each with 3 frequency settings
- subwoofer level can only be adjusted by digging through Menu settings
- supports Sirius satellite radio
- supports Bluetooth profiles: HFP 1.5, OPP 1.1, PBAP 1.0, A2DP 1.2, AVRCP 1.3
- separate High-Pass and Low-Pass crossovers for mains vs subwoofer
- dedicated 'Phone' button
- 'full-dot' LCD
- supports Bluetooth adapter but not included
- includes HD Radio
- parametric EQ has 3 bands each with 4 frequency settings
- subwoofer level adjustable directly from EQ window
- no support for Sirius satellite radio
- User Manual has no details about Bluetooth profiles
- no separate High-Pass crossover for mains; just 'on/off' ?
- dedicated 'Tag' button for HD Radio which doubles as 'Phone' when used with bluetooth
- old-style 'segmented' LCD lettering
I'm happy to see the additional EQ frequencies but wish they'd included even more. Also, I'd like to know if the bluetooth support has been improved. My current setup (XR810 paired with HTC Hero running Android 2.3.3) has inconsistent phonebook support and also is missing any audio display functionality (which I think requires AVRCP 1.4).
UPDATE: Ha! No sooner had I written-up all this then I noticed the following PDF on the JVC product web-page. It shows that the KDR720 has the same level of bluetooth audio support (as the XR810) but not the phonebook support. It also looks to have superior radio-tuner performance, in general (not just with HD).
