Our take on the Accele USBRHDMI

Tidy up your dash

The best part of a car stereo installation is the moment after you've pushed that last piece of trim back into place and your grand vision is complete. If you used the Accele USBRHDMI 6-foot extension cable, your dash will look even cleaner. Its surface-mountable socket gives you convenient access to your new car stereo's rear USB and HDMI ports. Mount the socket wherever you need it most to plug and unplug your media devices. Warranty: 1 year.

Looks great like a Factory installation everything works on my Samsung S8 plus for android auto. Going to try HDMI cable next for mirror link.

HDMI & USB Extension Cable: The Accele 6.25' HDMI & USB extension cable with mounting bracket (part # USBHDMI) connects to the HDMI input and USB port on the back of your in-dash head unit and provides a convenient connection for your HDMI component and USB device.

Note: This cable is not fully compatible with Apple CarPlay or Android Auto.

Male & Female Connectors: The 6.25' HDMI & USB extension cable features male and female connectors. There is a male HDMI connector and a female HDMI input. There is also one male USB (type-A) connector and one female USB (type-A) port. The male connectors plug into your head unit's rear-panel ports, while your devices are plugged into the female jacks of HDMI & USB extension cable.

Mounting Options: The Accele HDMI & USB extension cable with mounting bracket offers two mounting options.

Why did you buy this?

need it for my car stereo [ LOUIS R  Jan 08, 2017 ]
Installing this outlet will complete the installation in a professional manner. The system will be much easier to use, look better, and should be installed during the initial installation or be much more difficult or expensive later. Best for all. [ C  Nov 22, 2016 ]
Easy hookup to back of,sterio [ Jesus  Jul 26, 2016 ]
Clean installation and easy access to inputs. [ Gordon  Jul 17, 2016 ]
I chose this product to gain easy access to the HDMI and USB ports that are in the back of the head unit. [ John  Jun 30, 2016 ]
Simplify conection of my phone [ Robert  Mar 29, 2016 ]
I'm going to use it to access my hard-to-reach HDMI and USB ports on my smart television. [ Nicholas  Mar 01, 2016 ]
Availability for Andriod Auto function for my phone and also better USB connection for stereo. [ Steve  Feb 02, 2016 ]

5 questions already asked

I can confirm that the USB connection is fully compatible with Apple CarPlay on a Pioneer AVH4200NEX. [ Bryce  Feb 12, 2017 ]
I have this port on my avh-4200 and haven't had any issues with apple car play. I originally wanted to use the iDataLink Maestro ACC-USB-RAM in my ram pickup but that one does my work with CarPlay but it did work with CarPlay. I bought this one as a replacement and I have the idatalink plugged into usb2. The setup works great for me so far. [ Chris  Feb 10, 2017 ]
Yep, I agree with Keith and Zak. Android Auto is very picky with the USB cables you use. Using this adapter made the input continue to pop in and out of the sources menu and never held a connection for more than a half second. Glad you noticed this disclaimer before buying, I didn't haha. But it fits perfectly in the little pop-out on my dash, it's a shame really. I think I might try to work some exacto knife/super glue magic to install the stock cable in the little rubber mount... [ Scott  Feb 10, 2017 ]
I couldn't give you a definitive answer but my guess is that it's word as not "fully" compatible because you'll still need the HDMI adapter cable from Apple to be able to connect your phone to it. If anyone has a more definitive take I'd also like to know. [ Scott  Feb 10, 2017 ]
Do not get it if you plan on using car play. It kind of worked but like a skipping CD. Car play is cable picky. [ ZAK  Feb 10, 2017 ]
I own this product and seems to work fine with my apple car play. I believe apple/android compatible are more of a specific spec approval from apple/google. [ Keith  Feb 10, 2017 ]
I have a Galaxy Note 4 and it does NOT charge the device, only transfers data. It shows the lightning bolt on the screen like it's charging, but does not seem to charge it. Will driver around for hours and it doesn't go up, so I'm guessing its transferring data only. [ Ladd  Jan 19, 2017 ]
Yes , I charge my phone and also Ipad. [ Herbert  Jan 18, 2017 ]
Yes, ithw USB port will also charge your device [ JEFFERY  Jan 18, 2017 ]
It depends on the device that the USB is plugged in to. If your stereo has a usb charging outlet and you plug the extension into that outlet, then yes it will charge the device. The cord is just an extension and does not have a power supply. [ Chris  Jan 18, 2017 ]
Yes [ mervin  Jan 18, 2017 ]
Yes [ Jeremy  Jan 18, 2017 ]
Yes your flip cover will still close and funtion [ Antonio  Jul 29, 2016 ]
I'm not sure about your Sierra but it should. If you remove the lighter receptacle you should have a space that the until will fit into. It's very easy and I highly recommend it. The wire is long so you should zip tie it up so it doesn't take up a lot of space. I love mine. [ STEVE  Jul 29, 2016 ]
Yes it does, no need to drill a new hole [ Devin  Jul 03, 2016 ]
I drilled a hole , but it looks like would fit. [ Herbert  Jul 02, 2016 ]
Yes,I used an existing cigarette lighter hole and it fit perfectly. [ Matthew  Jul 01, 2016 ]
Yes, you can connect the Accele USBRHDMI to the rear panel USB and HDMI connections on your Pioneer AVIC 6100NEX for convenient access to connect your Samsung Galaxy phone. I hope that helps. My Bio: [ Larry  Mar 25, 2016 ]  Staff
