Hello guys.. I just had a Pioneer AVH x5500 installed in my truck, and I have seemed to encounter a problem, which I am hoping is an easy solution.

My installer wired my iPhone data cable to my center console. But here is the kicker - he never bothered to tell me that now the USB flush mount he also installed in my dash would be useless. I guess it's one or the other being the head unit only has one USB input. The problem is that the cable he installed is useless to me until I download the iPhone 5 update.. WHICH I NEED TO DO VIA USB!!! Uh so frustrated. I would have hoped he would have told me the USB on my dash would be disconnected, or at least would have downloaded the update before disconnecting it being I told him I had an iPhone 5.

I guess my question is.. how do I use the USB flush mount in my dash AND my iPhone cable he wired into my console? He said I might need a DC powered hub? Or is there another way to accomplish this?

I'm having a bit of trouble understanding what your installer did here as if you do have the CORRECT adapter needed for the Iphone 5 = CD-IV202AV - It has a usb input wired into it in addition to your phone and HU connections..... ???

I am looking at the photo of the CD-IV202AV - and I do see a USB female end - which for some reason I can't even get to due to being hidden under my console. So I wouldn't need a splitter? Is that supposed to go right back to the flush mount he installed? I hope I am explaining this correctly.

Ah - that female end is going to my lightening cable.

I want to use my iPod cable - and a USB if I choose to - and can't do both right now. That's the gist of it lol

I can't possibly be the first person who wants to use a USB or iPod in their car lol

I'd think a DC powered USB hub would be common. Maybe not.

Does it have the Blue Pioneer P-Bus input on the back of it? If it does you can get an adapter for that I'm pretty sure, But this is what I'd do then... Link: Newegg.com - ORICO Bokcore BC-U3H4 -SV Full Aluminum 4 - Ports USB 3.0 HUB 3.0 with Premium 12V Power Adapter & 3 Ft. USB3.0 Cable (http://www.newegg.com/Product/Product.aspx?Item=9SIA1DS0PS1256) - I'd hard wire up one of those then you'd have 4 ports ;)

I'm having a bit of trouble understanding what you're saying as well. So you have one USB input on the deck, and two in your vehicle, going to your deck; an iPhone cable, and a USB plug in the dash, correct? But, only one or the other works at a time, and you can't use both at the same time? It sounds like this would be a limitation of your head unit, not the wiring. Someone else correct me if I'm wrong, but wouldn't a splitter still create the same conflict at the source unit?

Well YES - he can only use 1 device connected at a time, but I think he's saying his other dash mounted usb is not even connected at all???

I had the installer flush mount a USB jack to my dash so I can listen to music via my USB drives. I also had him install the iPhone kit. They both require USB however - but the back of the head unit only has one USB input - so I can only listen to music via my iPhone, and never a USB drive. I'd like to do both because I don't always have my phone on me.

Its not that I would want to use both at the same time (obviously), but now I only have the option of using my iPhone as a music source. And I want to also have the option of using my USB thumb drive as well.

I guess my wording is wrong - I am looking for a hub, not a splitter. I basically need 2 USB inputs, rather than the one that the deck gives me.

You really might be able to get away with a regular plain old non-powered 2 way usb splitter since you will not be using more than one device at a time, if not refer to the link I posted above that one works on 12v dc ;)

Ok. Yes like NIHL8ION said, you could get away with a non powered splitter. A single USB port can supply up to like a 1000 something additional USB ports. But, if you PAYED someone to do this installation for you, and it was done improperly. I would take it back and have them fix it. There's no excuse for someone to charge you for work and it not be done right.

Thanks for the reply. I'd think it would work as well.

Has anyone actually TRIED it though? Would hate to buy one - have my installer rip everything apart again only for it not to work.

I haven't used a splitter on a head unit before, only computers. But it should all work the same. How exactly did your installer add the secondary USB port in your dash? IE, what's it running to?

ButteryNipples
08-27-2013, 05:49 PM
It's not running to anything. I guess he thought I'd rather have one or the other, and not both.

So he just cut your dash to install a plug that doesn't run to anything? Seems like a totally incompetent ******* to me. Add a splitter then. Heck, do it yourself, I wouldn't allow someone like that to touch my vehicle.

I've got a non powered 4 port usb hub somewhere around here... I will try using it on my Pioneer HU's USB input with my phone and a few different thumb drives & see what happens... I'll post the results as soon as I get done testing this later on...

Yea I was a little upset. I understand it's a limitation on the head unit itself, but you'd think he'd tell me that I can only use one or the other rather than just pick himself. Honestly, I'd use my USB filled with music over the iPhone.

Thanks NIHL8ION - very curious to see what you come up with on that. I am still shocked that I appear to be the only one that ran into this issue lol.

I went ahead and bought this -
Amazon.com: Tek Republic TUH-300 USB 3.0 4 Port Portable Hub: Computers & Accessories (http://www.amazon.com/gp/product/B00D4VLMBI/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1)

But if it doesn't work - oh well - USB hubs never go to waste :)

one or the other, either way you can only listen to one at a time.......... also you would take your iphone with you when you left the car. i'd ask him to just run a usb extension, so you can have your ipod or usb plugged in without having to rewire or anything

Should have just had him leave the female end available and not hook up the adapter behind the dash. But now you have to take it out and do that yourself.

I agree the installer should do what you need and you should have bought a HU with dual ports.

here is the issue I see with a hub - i don't think the HU OS/software is able to assign drives the way a PC can. And it will vary with each specific head unit, and if you draw too much current you can damage the HU (depending on how it was designed). ideally, a DC powered hub would resolve the power requirement issue.

I just want to use either or. I am shocked no one has ran into this before. There are times that I want to listen to music from my iPhone 5 (along with using the Waze app etc on the screen) - and there are times I want to use USB. But with only 1 USB input on the back of the Pioneer deck, it's not possible. The USB flush mount obviously uses a USB input, as does the iPhone cable kit. There is no way to use both. You can use one or the other. If the Pioneer had 2 USB inputs - it wouldn't be an issue.

My installer surprisingly never ran into this issue - which I don't understand. I'd think if a head unit advertises iPhone capability, AND playing music from a USB drive - that I would have the option of using either or, not just one. He suggested using a DC powered USB hub behind the dash. Where other people said a basic self powered hub will work. So, I went ahead and bought a USB hub on Amazon that has 0 negative reviews and will try it when I get it.

I am so frustrated over this. You'd think 2 USB's would be pretty common on the back of this head unit being they advertise the deck as doing both.

We mostly all do our own installs and make it such that we wouldn't run into this problem because everything we need to swap out is accessible.

OK - Well I've got the Pioneer DEH-80PRS which DOES have 2 USB inputs, but I went ahead and plugged my cheap little D-Link Non-powered usb hub into it and I was still able to access what I had plugged into it - Tried my GS3 Android phone & a few different thumb drives and they all functioned OK when plugged into the hub connected to one of my USB ports as long as only one of the devices was plugged in at a time so YES - you more than likely can have it setup to where your other dash mounted usb extension would function, but only if your phone is unplugged when using it as long as your Pioneer reacts the same way as mine does ;) Hope this helps...

Thank you so much!! That is very promising!!!
