Bluetooth AVRCP / iPhone 4

While test-driving a 2013 Elantra, I connected my iPhone 4 via Bluetooth to get a sense of how good the audio would sound. I noticed that I was not able to skip tracks with the steering wheel controls, nor did music playback stop on my iPhone when I shut off the stereo. Does the system not allow for AVRCP control?

The salesperson suggested that there's a setting on my phone that I can change to make this work, but that doesn't sound right to me... my wife's Acura Bluetooth system can control my iPhone playback without issue.

Any advice?

You need the special Hyundai cable to connect to the system to use those controls.

Hmmm... I found an Elantra manual online (Hyundai Elantra owners manuals, user guides, repair, service manuals), and it states that "the audio system supports Bluetooth® A2DP (Audio Advanced Distribution Profile) and AVRCP (Audio Video Remote Control Profile) technologies"

How is the Elantra implementing AVRCP if not to allow for remote control of Bluetooth devices?

I don't know what you are reading on that site but this is what I found there:

Some iPod devices, such as the iPhone, can be connected through the Bluetooth® interface. The device must have audio Bluetooth® capability (such as for stereo headphone Bluetooth®). The device can play, but it will not be controlled by the audio system.

Deactivate (turn off) the equalizer function of an iPod when adjusting the audio system’s volume, and turn off the equalizer of the audio system when using the equalizer of an iPod.
When the iPod cable is connected, the system can be switched to AUX mode even without iPod device and may cause noise. Disconnect the iPod cable when you are not using the iPod device.

It states that the Elantra's Bluetooth audio system supports both A2DP (streaming only) and AVRCP (streaming + control) protocols. A2DP is streaming only, AVRCP is streaming + control. All I'm wondering is: if Hyundai's intention was to allow streaming only, why would they bother including AVRCP?

Bottom line: you need the cable if you want to control the iPod/Phone with the cars audio system.

Right, I realize that. Just thought someone would have an answer... and with that:

This does not seem to be entirely true. After poking around some other forums, the real issue seems to be that iOS 6 (the current operating system for iPhone) implements AVRCP v1.4 a little differently than other phones, with a deviation from the Bluetooth standard. iPhones with older versions of iOS (and other brands of smartphones) apparently seem to be controllable from the steering wheel over Bluetooth. Seems like it's up to Apple to become compliant.

Thanks for your help.

Nope. Just took delivery on my Elantra, and the Apple 30-pin cable works just fine, even with the steering wheel controls. Furthermore, I am also able to control audio streaming from my iPhone over Bluetooth as well (the steering wheel controls work here, too).
