Hi,
Does anyone have any experience from using a USA Spec PA 12-TOY iPod Interface on the Toyota 58812 pre-installed stereo? I have a 2005 Rav4 and according to the manufacturer (USA Spec) it should work with my car / stero but obviously it doesn't. Does anyone have an idea if is possible to use this combination or not?

Question two: Does anyone know what the cable(s) currently connected to the cd changer port does? When I disconnect the connector the radio won't work.

Kind Regards

Martin

Hi Martin

I wonder if you might be better to post your question on the US owners club site;

I cant help you but maybe somebody there might.

Maybe, but I thought that maybe the European versions are more similiar than a European and an american, that's why I tried here...
I still think the problem is related to the Rav4 more than to the iPod interface and since I have a Swedish sold vehicle...

This Ipod interface for the newer 4.3 does show the connection into the changer interface;

I can only think that the head unit must pick up a feed from your CD installation. Can you check it with a volt meter?

Strange that pulling the avc-lan/iebus/cd changer connector should stop the radio working.

From this link

It looks like the 58812, has the older avc-lan connector (7+5 pins). The pin out for this connector is shown here:

From past experience, I'm fairly certain that the cd changer should be getting it's 12V feed from the radio (via pin 1 and 10 of the avc-lan connector) and not the other way around (i.e. the cd changer feeding the radio). Normally the radio power supply input is on another connector (probably the 10 pin connector in the 58812 picture, Can't remember exactly, but could probably find out with a bit more digging). Of course:

1. If the 12V output (pin 1) from the IEBUS connector is just a simple PCB track inside the radio to the usual radio 12V supply connector pin
2. Your normal radio 12V harness feed has been disconnected for some reason and
3. 12V has been connected into to your existing CD changer harness for some reason

then yes, disconnecting the CD changer cable, would stop the radio working.

With the remaining harnesses connected, if you can do it carefully, a voltmeter between pins 1 and 10 or possibly pins 6 and 10 on the radio avc-lan connector should indicate whether the radio is getting any power and whether it is going to supply any power to the ipod interface.

Maybe things are wired up differently on this model, than what I have experienced, but I can't think at the moment why that should be.

Cheers.

Thanks for your answers. I don't think the radio get its power from the connector, because the cd-player in the stereo still works and I can you the trip computer. I just can't listen to the radio. Really weird, but I will check the links you gave me and maybe I can figure something out.

Cheers
