I have both an avic-n2 and an avic-n3. Now my question is if I take an avic-n3 brain and put it to an avic-n2 will I get the extra functionality of Ipod, XM, and Sirius? I have seen this on ebay and thought that it might work. and suggestions. I really would like to update my wifes car also.

From what Ive read previously, the brains are all the same and interchangeable. I thought the XM/iPod designs were built into the headunit. (I could definitely be wrong tho!)

I know from a previous post that a microcontroller in the brain is different. There where not any other changes noticed between the two.

also in the description on the upgrade for ebay he mentioned updating the PCB not the chip. I wonder if someone has any information or can get the new PCB and supplier for upgrades?

AFAIK its the head units that are all the same and are interchangeable. Having the n3 head unit will not give you the added functionality present in the n3.

Plus, without the switch on the N3 brain, you'll be unable to do the bypass.

You could still have it bypassed such as I do in my wifes N2 solder the points. Now will the N3 Brain with a software update from my N3 give my wife N2 the capability of the N3. IE all of the new menu option especially for the Ipod?

It should. I beleive the new gui for the ipod are built into the n3's brain. At least that's what I've been led to beleive. You said you have both an n2 and n3 right? Why not try it out first?

I am thinking about it yet I do not know what the downfall would be from going back ot the old brain after I update her software.

You can use an n3 brain on a n1/2 unit and then put the n1 brain back on it and it is the same n1 that you remember...

 

And by the way, This modifaction IS HARD! I finally have done 3 correctly...I punked the first one though...(one of the few benefits of owning a shop these days is having a few spares around! )

 

If anyone is interested in this modification, I will do it for $250 (including the chip) and insured returned shipping.

 

Thanks
