iirc since the N4 does not support mass storage mode, and the x50bt only supports mass storage, they dont get to negotiate the charging voltage, which kind of sucks. You can get an usb cable that only has the 2 power pins connected to charge the phone from the radio, though.
You wont be able to use the cable to transfer data, of course.
The user expirience with an iphone is far superior, as i transfers audio over usb and gets charged at the same time

I can confirm this. Touching the DISP (display) button will cycle through Artist / Song Title.
KD-R730BT

It won't charge the Nexus 4
You will need an external usb charger that would plug into your 12V socket.

The KD-R730 has two usb ports. The back usb is typically where you connect your BT receiver.
Autoplay on KD-R90BT etc
I know this is pretty old, but I'll post here in case someone else is having trouble getting this unit to auto-play. I think this probably applies to any of the JVC units that use a bluetooth USB module. E.g. I have the KD-R90BT and am using it with a Nexus 4 - I opted for the R90 for the multi-line track/artist display and better EQ settings, both of which work well. As previously mentioned it can take around 15 sec to make the BT connection but it's not a big deal.
I initially tried to make a tasker profile that detected once the bluetooth was connected, and then toggle play/pause to start the music, but it did not work. With the help of this: https://groups.google.com/forum/#!msg/tasker/iiAUa-dmaug/-KoPG-LXArQJ it turns out that the head unit typically makes two connections (probably related to phone book sync etc) in quick succession. The following works for me:
Profile: Car Stereo (48)
State: Bluetooth Connected [ Name:* Address:00:10:60:XX:XX:XX ] (use your own JVC bluetooth address here)
Enter: Media Toggle (43)
Task: Media Toggle (43)
A1: Wait [ MS:0 Seconds:3 Minutes:0 Hours:0 Days:0 ]
A2: If [ %PACTIVE ~R .*Car Stereo.* ]
A3: Wait [ MS:0 Seconds:3 Minutes:0 Hours:0 Days:0 ]
A4: Flash [ Text:Toggle pause Longff ]
A5: Media Control [ Cmd:Toggle Pause Simulate Media Buttonn ]
A6: End If
Essentially when the task is triggered, it waits 3 seconds and checks via the PACTIVE built-in variable whether the profile is still active (i.e. the connection has lasted more than 3 seconds. If so, wait another 3 seconds for unit to be ready to unpause, and then simulate the media pause toggle.
Hope this helps someone.

I have the kd-x50BT and I was wondering if I can reprogram arrow up/down buttons with tasker so whenever I press one, tasker detects the input and do a certain task (for example, rate it up/down if I'm listening to music, not pandora). Does anyone knows how to do this?
Also pandora thumbs up/down doesn't work for me, does it work for you?

In reply to a couple of comments above, I have been able to charge an N4 from the USB port on the KD-X50BT. We have one vehicle where that is the only charging source. I do recall noticing that the charge was very slow, even declining while running navigation. What helped was to enable "USB fast charge" with the app Trickstermod.

Pair multiple phones??
the specs of kd-x50BT states we can pair up to 5 devices. But I can't figure out how?
Whenever I pair another device, (By going into Menu-Bluetooth-Initialize-Yes), the newly paired device replaces the old device.
I checked in Menu-Bluetooth-Unpair- and it only lists the last device I paired.
Can anyone help?
Thanks in advance.

I have two KD-SD80BTE units and a KD-R731BT (all very similar to the KDX50BT) which have worked flawlessly with my Nexus 5. However starting with Android version 4.4.3 I can no longer pause the playback using the menu button.
Has anyone else noticed this problem?

Hopefully you have found this answer already, but you don't want to initialize Bluetooth as that deletes all the connections. Just initiate the connection from the new device. We have five devices paired without issue.

Didn't notice until you said but now I come to think it's true! Menu button goes back a couple seconds.
Sorry to revive this old thread but I noticed the same thing with Spotify. I can resume with the menu button but I can't pause. Did you ever figure this out?

11Though I would post this for anyone looking for bluetooth car options. I've been using this deck for the past week and love it. For years I used FM Transmitters, but after breaking/losing/etc several and not loving the sound quality, I bought a deck with auxillary input. That was fine, but still wires everywhere (especially when charging).
I purchased and installed the JVC KDX50BT. It is their entry level bluetooth deck, and does not have a CD player. Thats fine for me. I drive a Jeep and the CD players always end up getting dust inside and stop working after a few years (and I never use them). I ordered from Crutchfield for $100 shipped: http://www.crutchfield.com/p_105KDX50BT/JVC-KD-X50BT.html?tp=5684
In short, I love it. The bluetooth streaming audio sounds great, and although its hard to do an A/B comparison, I believe it is better quality than the old deck with auxillary in. Bass seems to not distort at higher volumes as much as the auxillary in. This would make sense if the stereo itself is doing the digital processing. It also shows the current song information. This is "BT Audio" mode, and will basically stream whatever audio you are currently playing from any app.
It also has Pandora capabilities. This is called "BT Pandora" mode and it will display your current station info. Even better, you can thumbs up or thumbs down a track from the deck itself. When you do this, the Pandora app recognizes this and displays a screen that does not allow user input from the phone. It is kind of annoying as I plan to put in a car mount and wouldn't mind being able to see the album art. On the other hand, I have put in about 3 hours of listening so far (off and on) and haven't had a commercial yet, so I'm not complaining too much! I was going to upgrade Pandora but now I may not need to.
There is also an external microphone you can mount anywhere in your car to use for calls. I haven't used it much but initial reports from my friends are that sound quality for the other party is good.
It isn't completely bug free with my Epic Touch (Running Mijj's Blend ICS right now). Sometimes it will switch over to the Pandora mode in the middle of a song without me telling it to. This is annoying, but it is quick to switch from Pandora mode. It doesn't always display the current song information correctly in BT audio mode, but most of the songs I'm streaming from my phone I don't need to know the title. It does not show song info from Spotify. It also will not display info from my podcast player (beyondpod) but I don't really care about that. The stock music apps seem to work best for song info.
I am guessing many of these issues are with the Bluetooth protocol and the way our phones handle it. It could also be the fact I am using a custom ROM rather than stock. All issues are minor annoyances.
Other pros:
-You can change the colors of the display to pretty much anything you want, and have different schemes for night and day.
-Easy to pair.
-Two USB inputs (front and rear) but if you are using bluetooth, one of these will be taken up by the JVC USB Bluetooth adapter.
-USB inputs are 1.0mA rather than the standard 0.5mA for faster charging. (I still use my car charger as it is positioned better for my needs)
-Radio does seem to have great reception; finding quite a few more stations that my old deck.
Other cons:
-Radio station presets awkward to use... you have to "scroll" through them rather than just hitting button 1-6. I've been playing with the bluetooth too much to really get used to it.
Meh:
-I also have a set of bluetooth headphones. If I am listening to the headphones and get into the Jeep, I have to either turn off the headphones before turning on the stereo, or manually connect in the bluetooth settings menu. As far as I know this is a bluetooth limitation and not the fault of the deck. It would be sweet to have it transfer automatically to the new source when it finds it, but not sure this is possible regardless of the setup.
-There is a JVC app that allows some touch based controls on your phone. I haven't used it much but it does seem to work OK.
All of that aside, the real reason I bought it was for the ease of getting into my Jeep with my phone in my pocket, having the phone automatically connect and begin streaming high quality audio to the stereo within about 30 seconds of the car starting (it takes a moment for the phone to connect). On short drives the phone doesn't even leave my pocket. So far, I couldn't be any happier with the results I am getting, especially for $100.
................And I just found the following deal that gets it down to $81 shipped. That sucks for me, but even at $100 it is a steal!
http://slickdeals.net/permadeal/698...AQFjAA&usg=AFQjCNE28H5hsYS9gz484lxxo97Nukzipw2Came here to find out if USB hub would work and thought I'd share.
Purchased one of these from Crutchfield a few months ago and couldn't be happier.
First of all, got for $80 total with all the installation stuff. It was $120, but then used the $20 off promo code. And for anyone with a Discover card, you can use your cashback to get $100 Crutchfield gift card for $80.
Bluetooth works fine for me. A few startup connection issues on occasion, but turning BT off/on on the phone fixes that.
I went the way of a USB hub also to keep my front port open. Got a Belkin 4-port hub from Amazon for $5. Haven't tried multiple USB drives, but it works fine with a 32gb and the BT module connected.
The Pandora integration is very cool. I love being able to thumbs up/down songs from the unit.
Google Music works well and depending on your rom displays the ID tags.
The dash menu is klunky, but it's standard issue for aftermarket radios like this.
The JVC app is junk. I was hoping it would allow for better scrolling through the usb mp3s, but all it does is mimic the basic remote functions (play, pause, skip, mute, etc.) with touch gesture control.
Did the install myself. Never installed an aftermarket before. It wasn't the hardest thing, but it wasn't the easiest either. Took me about 3+ hours, mainly just double checking stuff. If I did another one, I bet it would take half as long. The Crutchfield directions helped once I got my bearings, but they weren't the most detailed for a rookie.
Very nice unit considering the features and the price.2
Are you using Google Music? I'm going to try different apps tomorrow and see if any make a difference in that regard.
and I actually did find a software update, http://www3.jvckenwood.com/english/car/support/navi/r50/unit_soft_download.html2
Hmmm, this is strange. Google Music shows the ID3 tags for me. I have noticed a handful of times that it does not update after a track change, but I'd say less than 10% of the time. I'm using an ICS based rom on my epic touch.
Have you tried using the JVC app? I don't use it but it might be worth a shot.
Edit: I just ordered a GSM Galaxy Nexus and will be switching over to prepaid, so I'll let you know if it works with that phone.
Sent from my SPH-D710 using xda premium1Nice find. I was just looking at a Sony Deck earlier that does the pandora control. It's a bit more expensive but also lacks a CD Player and has an OLED Screen or whatever.
I have a Sony now and it uses the same wiring harness so would be a quick install for me and I've always loved my one I had now.
The BT Streaming and Pandora Control are what i'm after though.
