The 710BT offers lots of features, some of them good, some not so good.
BT works extremely well, probably one of the better implementations I've used. iPod control is also very good for a HU control. Better than many others.
There are lots of nice features like being able to switch the display between multiple layouts, voice command, a large array of input options, SW controls, 7-band EQ, and many more. I can't think of any other HU that offers the shear amount of features that you can find on at this price point.
The display offers lots of options from 3-line text information, to graphic images, and even VU meters. If the display is a major concern for you, you will be very pleased with this HU's display offerings. The display is crisp and clean, it does reflect quite a bit though, and since there is no tilt option, you'll find yourself placing your hand in front of the display to read it.
The included steering-wheel remote is practically useless. It uses infrared, so you need line-of-sight for it to work. However it mounts to your steering wheel, which is constantly moving and losing line-of-sight.
I don't use the built-in amp, but it is very powerful, and has very low distortion. I was able to turn it almost completely up without any distortion at all. Very clean. The 4V pre-outs are fairly clean, but I did get a bit of noise on my amps with them at lower gain levels.
For sound features, it offers a 7-band EQ, HPF & LPF, Subwoofer phase, adjustable source levels, balance, fader, loudness, and bass boost. There are 5 preset EQ settings, and 2 custom settings. You can modify the 2 custom settings.
That sounds like a lot of sound adjustment options, but I had a really hard time getting my system to sound good with these. I'm running 2 pairs of Infiinty Reference components in the doors, with an Infinity amp powering them. I'm also running an Infinity 10" sub in the trunk with a mono amp. My last HU offered Time Adjustment and a 9-band EQ. I set it initially and rarely touched it after that. The sound stage was very impressive with the old unit. I can't seem to replicate that with the 710BT.
I tried creating a decent sound stage using the balance & fader settings, but it always seemed the sound was coming from just below the dash. I then tried adjusting the EQ. One of the custom settings allows adjustments on each frequency in 6db increments, while the other offers 6-4 db increments. I find these to be somewhat limited. The sound always seems a little muddy to me. I figured I would turn off the sub, and use the crossovers to get the comps sounding as good as possible, but no matter what I do, I can't get the sound as flat as I would like. I didn't think I would miss the TA settings, but it seems they would have been very handy. Also there is no level adjustment for the sub, so I have to keep running back to the trunk to adjust it.
All in all if you don't care much about sound quality you'll probably like the features of this unit. If you want your music to sound good, you might want to look elsewhere.
