Default 2014 Outback: USB Plug Problems

My iPhone 5 and 5S both seemingly short the USB plug when plugged in. They are recognized and charge for a few minutes but then the USB plug goes dead until I turn the car on and off.

I took it to the dealer and their service dept said that they can't find anything wrong with the USB jack.

Anyone have the same problem?

I'm guessing the amps for the newer phones is too high and a resettable breaker is blowing on the plug. But, 60 million iPhones with lightning connectors were sold last quarter.... surely I can't be the only one having this problem.

I tried plugging my phone in (a Nokia Windows Phone, so completely different) and I never saw it even try to charge. I was disappointed but didn't look into it further as my phone can last a full day as long as I charge it before I leave. I'll take another look at it tomorrow.

Given the Supplied USB is for audio usb etc... to the Audio system, why not buy a 12V to 2x USB Power and charge your phone from this instead ? We can even get an otherwise fussy Samsung Ace to charge with this. My Samsung S4 and iPod are also fine.

Some USB ports will give a "not charging" message with iOS if there's not enough amperage on a communication port only. I saw this more with my iPhone 4 than my iPhone 5. It may be charging, albeit slowly.

I'd look at the head unit itself. It is the one dropping the charging connection, and the cabling/port itself may actually be fine.

However, the iPhone negotiates the charge rate when it connects. Only when the port advertises that it is a 1A port does it draw more than 500mA. In practice, it rarely needs more than 750mA. So the current draw should not be a factor unless the head unit is advertising 1A to the iPhone and then shutting it off later.

I didn't have this problem when I was using the stock head unit in my 2013, but I'd still bet on the head unit being the source of the problem.

Default 2014 Outback: USB Plug Problems

I have the exact same issue. Iphone 5 and Ipod both seem to short out the USB jack until the car is restarted. It works for a few minutes and then dies again.

Because if you are like me and listen to music through your iPhone, if the USB port isn't working, Bluetooth is the only other option, which has a lousy sound quality.

Default 2014 outback USB port and Auxillary cables not working properly

I purchased my 2014 Outback less than 2 weeks ago. I'm currently at the dealer. I tried using different devices, different cables (direct from apple, not from apple) and still the problem persist. I get a message reading "check device" randomly and the music stops. I am also experiencing a lot of feedback static when I use the auxiliary cable. ULTRA ANNOYING!
Serviceman said they are experiencing these problems in all models with the multi-port systems and isn't aware of any fixes for the problem.

It may be a firmware thing with either the phone or the head units. Back in the day when the iPod touch was super popular, they were incredibly picky about what they were charged on. Had to use an Apple cable and a port with enough current capability. I'm sure they're a little less restrictive now, but it might be worth checking that your phone's software is completely up to date.

Picked up a 2014 2 weeks ago, and neither my 5s nor my wife's 5 will work for more than ~10min through the USB before it goes to "check device".

Really annoying, as we listen to iTunes Radio and change the stations using the head unit, which isn't possible over bluetooth. The sound quality is much better than bluetooth as well.

Has anyone gotten anywhere on this?
