    Just wondering if anyone knows if it is possible to use the 3.5mm headphone jack to display video if you have the correct cable?

    I know we have the HDMI out but my car only has component rca jacks.

    Thanks for any help!

    I know it works with a bunch of other phones but haven't seen anything about it working with the razr. Anyone?

    You know this because you tried it out? Or you are assuming?

    I am assuming because I have never seen any phone that would do this and Motorola would have touted that feature. Only thing I have seen that has the capability has been older digital cameras and even those aren't 3.5 mm, they are smaller.

    Either get a digital to analog box or change head units.

    I have seen 3.5 to rca cords for sale that say they work with cell phones right on the package...not sure what phones are capable though.

    There ARE 3.5mm to RCA cable adapters, but they will ONLY provide AUDIO Left and Right channels out on the RAZR. There would be no reason to give the audio port video capabilities as well, since there is an on-board HDMI cable connection (which by the way, also provides AUDIO), and it's simple to convert HDMI to Component as NoBloatware correctly commented on and provided links.

    One thing I DID discover though (slightly off-topic) which might be helpful information for some is that the USB on these phones ALSO provides AUDIO, and with the Navigation Dock, there's a cable provided that performs double-duty. One end has the MicroUSB for the back of the Dock, the other end terminates into a USB-A connection (the standard USB plug), which plugs into a dual-port car adapter, but it also has a pigtail that provides a 3.5mm Stereo Audio out, so you can bypass the headphone jack on the phone and make both power and audio connections by simply putting the phone in the Dock and pressing down the USB connector. :icon_ lala:

    I have it and it works like a charm! Also, since I don't have to plug in a headphone cable anymore, I only have ONE cable running up to the Dock, and there will also be less wear and tear on the rather delicate headphone jack. Way to go Moto!

    So once again, have you tried it out or so you assuming it doesn't work with the razr?

    When you need a power converter and 2 other parts, I don't called that a simple hookup. As mentioned above about the HDMI out.

    Thanks for info on the audio issue, good to know.

    Sorry, I didn't mean to imply I had tried it. No, I haven't but I am 100% sure it doesn't work. Not that this is 100% confirmation, but the Motorola website (The New DROID RAZR - Android Smartphone - Ultra-Thin - KEVLAR Strong - SPECS - Motorola Mobility, Inc. USA) shows the specs, and for the 3.5mm jack, it says "Headset jack". One would assume that if it had Video out, it would be touted there. It clearly indicates HDMI under another section (see below).

    HEADSET JACK
    3.5 mm


    CONNECTOR TYPE
    Micro USB, HDMI® Micro
    Furthermore, outputting Video through the audio jack would require at least one connection inside the jack to lose its other functionality. Since the jack has only 4 conductors, Tip, Ring1, Ring2 & Sleeve, and since the Sleeve is the Ground, the tip is Left, and Ring1 is Right, the Ring2 is reserved for the Microphone input off of a wired headset. To give Video out, it would have to give up one of the two audio channels or the Microphone input. If other devices do this then perhaps they don't need the Microphone input.

    FoxKat, you have me wondering if you know if it's possible to use this feature to solve a problem of mine.

    My car has been wired so that I throw a switch and plug a iDevice cable (which they ran from somewhere behind my dash) in my iDevice and I can play through my sound system as well as charge my iDevice.

    When I got my Razr I got the CableJive dockBoss adapter which translates the audio signal from a 1/8" audio plug to a iDevice docking system. This enables me to plug into my phone's headphone jack and hear it through my speakers. But there's no charging. Using a cigarette lighter charger while playing music often results in "dirty signal"noise.
    Do you think if I could find an iDevice to microUSB adapter it would allow me to both listen to and charge through the same dash cable again?

    Sorry if this is a dumb question. I just keep thinking it should be possible without rewiring the car.

    EDIT: I found this version of a CableJive dock that seems to say it will do what I'm wondering about. If I'm understanding it correctly, this would enable anyone with an iDevice docking station to play and charge their phone though it.

    The cable above would give you what you want but you'd have to plug both connectors into the phone as shown in the picture. If you want to reduce that to only the MicroUSB connector, you could either purchase the Vehicle Navigation Dock I referred to from Motorola (sold at Amazon.com Amazon.com: Motorola 89525N DROID RAZR Vehicle Navigation Dock with Rapid Vehicle Charger - Car Kit - Retail Packaging - Black: Cell Phones & Accessories), or purchase just the Power and Audio USB cable directly from Motorola, and then purchase the USB A Female to MicroUSB Female adapter here (USB 2.0 A female to Micro USB B female adapter cable FF | eBay).

    With these two cable adapters you would reduce the number of plugs in the phone to just one - the MicroUSB connector (since it also supplies Audio through the Motorola Power and Audio USB cable).

    There's a picture of the cable on the Amazon site showing the three connectors (the sixth picture). You would plug the MicroUSB plug from the dockBoss+ into the USB A Female to MicroUSB Female adapter on the MicroUSB Female end, and then plug the USB A connector from the Motorola cable into the other end. Then plug the 3.5mm (1/8") audio plug from the dockBoss+ into the pigtail female 3.5mm (1/8") audio plug on the Motorola cable. Then you're left with only one cable to either plug into the back of the Navigation Dock or into the top of your phone. dancedroid

    For me, the Navigation Dock gives me the easiest and sleekest connection in my car. I don't have a plug into my car stereo, but I use an FM transmitter that ends in a 3.5mm audio plug, so I simply plug the Motorola Power and Audio USB cable's USB A connector (picture 6), into the dual-port USB Car Accessory Adapter (picture 4), and the FM transmitter into the pigtail right off of that USB A connector (picture 6), then the other end with the MicroUSB connector fits into the back of my Navigation Dock (also picture 6). Then I just put my phone into the dock, push down the plug (far left pictures 1, 2 & 3), to secure the phone and I'm done. To remove, I simply lift the plug and the phone comes out of the dock. This way, I don't even need to use the audio to audio cable (picture 5) at all. :biggrin:

    To solve any "dirty" noise created through the car power adapter, you would need to place a Ground Loop Isolator in between the audio port on the dockBoss+ and the phone's audio jack (or in the case of the Motorola cable - between the dockBoss+ and the female audio pigtail on the Motorola cable). You can get these at the local radio shack 9http://www.radioshack.com/product/index.jsp?productId=2062214), but as in the picture they're usually set up with RCA plugs on both ends, so you then need a dual-RCA to 3.5mm male audio converter on one end, and a dual-RCA to 3.5mm female audio converter for the other end. I had the same problem and I purchased the Radio Shack one, then I went the extra mile and cut off the RCA cable plugs and soldered on a 3.5mm female on one end and a 3.5mm male on the other, using heat-shrink tubing to clean it up. :happy3:

    While researching choices for you tonight, I just found this one by Pyle (http://www.amazon.com/gp/product/B0...=393185&creativeASIN=B004HJ35F2&redirect=true) or this generic one (http://www.amazon.com/GROUND-LOOP-ISOLATOR-3-5-APPLICATIONS/dp/B001EAQTRI) on Amazon.com, this one from Crutchfield (http://www.crutchfield.com/S-DDVRm43N0fB/p_127SNI135/PAC-SNI-1-3-5-Noise-Filter.html), and this one for real cheap, $5.99 including shipping on eBay (http://www.ebay.com/itm/MINI-3-5MM-NOISE-FILTER-GROUND-LOOP-ISOLATOR-CAR-AUDIO-/260741338139). Each comes with the right connectors on it already, so don't bother going the Radio Shack route. Unfortunately for me, I didn't see these before now, so I did it myself. :blink:

    ***EDIT*** Hey, why spend the extra money for the dockBoss+ when all you need is the dockBoss (http://www.cablejive.com/products/dockBoss.html). Then you won't need the converter cable either. All you'll need is the Motorola Audio and Power USB cable and the Ground Loop Isolator. :icon_ lala:

    The 3.5mm jack can be used for signal other than audio. I use Square to swipe credit cards on site for my business and the reader plugs into the 3.5mm headphone jack. It would mean writing code or having an app that sends or receives whatever signal you want through the jack.
    IMO the quality would be sub par compared to either the USB or HDMI connection.

    Thank you so much for all the time and research you put into this! I'm wondering if the last option (in the Edit) is the way to go as I already have the dockBoss. I also don't think I'll need the ground loop isolator then as I don't have a problem with noise when I use it with my iDevice so I think the install folks must have taken care of that when they ran the cable. The dirty noise only came into play if I plugged into my cigarette lighter for power for the phone so if I can skip the lighter, I don't think i need the ground loop isolator.

    I'm trying to find the audio/power cable as a standalone item and I think it's this ITEM NO. SKN6394A but there's no picture or tech info. If that's it, and I understand you correctly, I can plug the audio plug from my dockBoss into the Motorola cable and then the microUSB part of the Motorola cable into my Razr (and just leave the other part of the Motorola cable alone.)

    Alternatively, as I was looking for the Motorola cable, I found this Samsung microUSB to 3.5mm female.

    Couldn't I just plug my dockBoss (the one you linked to) into the 3.5mm end and the microUSB into my phone? That would be really easy assuming it would still conduct the power and sound.

    EDIT: It appears Motorola also makes a microUSB to 3.5mm adapter. Little more clunky but in this application it wouldn't matter much. Maybe it would be less likely to have compatibility issues?

    I couldn't be sure if the Samsung adapter will actually mate up properly from a pinout configuration with the Motorola phone, since I had one for an HTC phone similar to the Samsung above that I used to use on the HTC XV-6800 but it doesn't work with the RAZR, however the Motorola adapter works for certain. As for the power, if you have power coming from the dockBoss+, you could use the cable I mentioned. The dockBoss (minus the +) doesn't supply power so you'll still need a power source, and if the power source is dirty, you'll need the Ground Loop Isolator.

    The Motorola USB Dock Power Cable you found is NOT the cable I showed you which comes with the Navigation Dock (again visible in the photos on Amazon's page). The one with the Navigation Dock specifically mentions Power, USB and AUDIO as a part of its collective name, and you can see the separate audio Pigtail hanging opposed to the Micro and standard USB connectors in the photo. The audio pigtail comes off the back of the standard USB connector as one of two cables that come off the back of that plug. The one you referenced only mentions USB and Power and there is a USB Power only cable that doesn't have an audio pigtail.

    I will see if I can get the part number and order information for the Power and Audio USB cable.
