iPhone 5 integration help

Where are the AUX jacks in the '09?

I'll be interested to see if the later-model Nissan Nav systems can be firmware updated to utilize CarPlay. So far, Nissan isn't even out of the gate with CarPlay on any of their OEM Nav system head units.

I have had EXTENSIVE dealings with the iPod interface in the 09 Z.

2009 370Z IPOD -> A2DP Bluetooth Unit

The Z's that are equipped with the 30 pin iPod adapter communicate with the audio system via UART communication with the following configuration:

• 19200bps
• 8 data bits
• 1 start/stop bit
• no flow control

The 30 pin connector has both UART and USB interfaces available. It appears that the new lightning connector only has USB support. The interesting thing, however, is that the protocol sent over the UART is the same for USB.

So theoretically, if the USB interface was converted into a UART interface with the above specs, the communication between the iPhone 5 and the 09Z iPod adapter would be possible.

What is needed is something like this:

that has adaption from USB to UART.

If there is interest in this kind of adaption, I can try to take a closer look and try some experiments.

Didn't know there was another option since 09

But that looks like it would do the same thing Im doing now going thru two converters.

It looks like there is a product that does the conversion from Lightning to RS-232 already.

Lightning Serial Cable for iOS


If it supports the sync bytes that are needed to talk to the Z, it will translate the USB communication from the Lightning connector to the UART communication the car needs. I emailed them asking if it supports this. I will post their response. Using this adapter, or building one like it, it should be very straight forward to get iPhone 5 devices talking to the car like other older iDevices with the 30 pin connector.

The iPod/iPhone port and aux rca's are located in the center armrest area.

You will have to remove the extra cup holder in place IF you have one by pulling it up and out of the way.

IIRC, it requires a special cable to go from the car to a standard iPhone/iPod 30-pin connector. That could be a problem since there are some issues with data compatibility when using a 30-pin to Lightning connector that the iPhone 5 requires. Some of those non-Apple adapters don't work so well.

Yes that is correct.

The only issue now is that you would also need two converters

1. A converter for it to actually charge like the original iPhone 4

2. A second one to change the old style connector to the NEW lightning connector

This is how I use mine and I have not had an issue so far.
