I have had my new VM9324 in my car for a few days now and have the following comments:

1) I have used most every feature on the unit except the iPod interface (I don't own an iPod) or the verbal control, and everything works "as advertised". The stereo is a great value for a HD radio fan -- there aren't any other double-DIN touchscreen units with built-in HD radio in this price range.

2) I don't have an issue with the boot up time. Maybe people have an older version? The sticker on mine says it was manufactured in May 2010. It boots up in 15 seconds, and it will start up in exactly the same place (on a radio station, or on a CD track, or a MP3, or in the middle of a movie) as when it turned off... furthermore, if you're only out of the car for 20 minutes or less -- the unit merely "sleeps" and comes on instantly when you start the car, no waiting for a reboot. If your unit doesn't do this -- maybe it's wired up wrong?

3) I haven't noticed the HD reception issues either. If you leave the receiver in "Auto" mode, the stereo will do its best to switch between the HD and FM signal when it has to.... I have only noticed a slight "echo" a couple times, otherwise it handles HD signal dropouts just fine. The HD radio works as well as the Kenwood in my wife's car, I have no complaints.

4) I have had no lockups or spontaneous reboots. I have a feeling that those who do, are probably suffering from over-heating.. this unit gets hot! Be sure to leave space behind the rear fan.

5) Unlike my cell phone, the VM9324 does not play MPeg4's, WMV/ASF's, or AAC/M4A's. It does like MPEG1, MPEG2, and AVI video files... as well as WAV and MP3 audio. I will have to re-encode some of my vids and music.

6) I do concur that the user interface is problematic. There is no practical way to switch between radio stations while you are driving... the only buttons big enough to touch accurately are the Next and Prev station, you can't jump to preset 15 from preset 1 without a lot of hassle.. you'll have to get used to hitting "Next" 14 times to get from preset 1 to preset 15; the MP3 playlist handling is truly "WTF"?; most of the fonts are too small for just a quick glance (like the clock -- why is the Time page so darn small?).

Overall, I am happy with my purchase and would recommend this to anyone looking for a double-DIN touchscreen with built-in HD radio.... I consider it a good value. However, if you don't care about HD radio, you'd probably be happier with a different brand..

For folks who do it them selves it was easy no problems with fit or finish

Just a few notes, I am not using the voice control, satellite radio, navigation, or backup cam functions so I can't comment on those.

Pros:
- HD Radio works as advertised
- Basic iPod functionality works without the additional Jensen cable, just plug your iPod into the front USB port using the Apple cable
- Touchscreen is decently responsive, the interface is generally well thought out (first radio I can change the time on without having to get out the instruction manual)
- Good selection of outputs and inputs
- Low price

Cons:
- Takes ~20 seconds to boot up every time you turn the car on, so don't expect to be listening to the radio as soon as you start the car
- Display is difficult to read in bright sunlight
- No album art on iPod
- Takes a few seconds to skip tracks when using the iPod

i bought this unit after reading the reviews and was thinking it was going to suck. when i was installing it i had a little trouble becuase i found out my car had a factory amp installed. but once i figured it out. it sounds amazing, only problem is it takes a little bit longer to start up, but its bareable, just sit still in your car until it starts.

Put it in and works fine. I did a code thing which I foun on the net which meant that you could turn off the DVD no play when handbrake is on thing which is great!! Also fitted the reverse camera and auto connected it to the reverse lights. It works too.
Never installed a radio before, so I am very happy with how easy this was to do and how it has turned out. iPod interplay is pretty dumb, so wouldn't buy it if iPhone capability is the top of your list.

Just installed this unit today. I like the modular approach to the rear wiring. Not using the internal amp? Don't connect the wiring harness. Not using the backup camera? Don't connect the wiring harness. Takes about 15 seconds to start up - no big deal to me. DVD playback is pretty good, and the screen has a nice refresh rate. Controls are easy enough.

USB playback is GREAT - MP3s, AVIs, MPG, MPEG, it does a lot of formats and I'm very pleased with that. Browsing is difficult between folders, and is rather annoying. HD Radio works ok, but reception is rather weak - I recommend an antenna amplifier - which I had. Haven't figured out presets yet... seems more difficult than it should be.

Settings for the unit are pretty basic for the functionality it has... disappointingly general in nature. Overall though, for the price, and name brand I'm pretty satisfied with this unit.

Overall it's not a bad product, it actually made my speakers sound better, and the equalizer is pretty decent to, but like others have stated it takes quite a bit of time to boot, and if you are listening to the HD radio, and your HD isn't coming in clear it makes this rather annoying stuttering and echoing sound. The unit comes with a rotary volume control which is pretty much a must, because having an all touch no knob is a pain in the butt. The design is very nice, and the screen is crisp, bright, and responsive. I would recommend this product, because you can't get any better price for a DDIN head unit with already integrated HD radio.

I installed this myself, 2008 Nissan Frontier, in about 3 hours with the GPS system. Overall it was very easy to install and I had no major issues. The deck will use the factory brackets that are attached to the factory radio, which was nice. You will not need to use the adapter kit, just the wiring harness and antenna adapters. The GPS system has been used several times now and have had no problems, it finds it way everytime. The HD radio is awesome and comes in crystal clear. I have used every option this thing comes with but the bluetooth and have had no issues ever. The only nit pick I would have would be that the screen is a little hard to see with direct sunlight, but I believe you would have this with any screen. Overall I am very pleased with this unit and would recommend it to anyone.

I love this radio, it has amazing features however voice recognition is not accurate. It works when it wants to and I guess the only complaint I have is that the start up is kind of slow. Other than that it has amazing sound and features plus the screen is amazing I could actually see the screen during day time unlike older Jensen units.
