2004 Sebring Limited + RB1 Nav ... any hope?

yeah the RB1 is a CAN bus system no way to change the logo and steering wheel and vec speed wont work. So all u will get is radio a limited gps sorry.    and fyi  the 22way is the old way.

That's what I was afraid of. :(
 
In researching more since my post, it appears that the RB1 is expecting a J1850 bus protocol.  In looking at the OBDII on my car, I see that there is no pin two, therefore no J1850 (isn't this a Ford protocol anyway, why would Chrysler/Mopar make a radio/nav that requires it?).  Is there perhaps some way to pull it straight from the BCM?  Looks like the bus protocol my Sebring is using is single wire ISO 9141-2 (which makes sense). 
 
Thanks!

all of the speed info is encoded using the PCI bus system. Unless u are an electric engineer and can decode binary electeric code via 7.5 volts  be my guest. The BCM does not require any thing from the speed sensors ne way it will go stright to the Cluster for that. The J1850 protocol is generiic for any ones scan tools and will only access the PCM Engine computer not the other computers on the bus. The requirement for the radio to be on the bus is for several reasons one u have figured out by the radio steering wheel controls not working thats on the bus. Diagnostics for the radio, With the RB1 amp signals over the bus, and if u have fands free  thats over the bus.
Hope this helps ya

Thank you for the details on this.  I get the full picture now.
 
I have one other semi-related question.  Since I now must venture into the realm of the non-factory aftermarket systems in order to get the in-dash Nav/XM/etc. that I want, what about an adapter to allow the use of my built-in steering wheel controls.  I see that there is a conversion unit (SoundGate Remote6) but given the seeming oddity of the Sebring Coupe models (Limited included) will I run into the same 'bus' problems with this product?
 
Thanks!

if u go after market u can almost forget about the steering wheel controls unless u get a good enough system that has a way of using the pci bus inputs from the factory harness. U will haft to see or call up the specs on the system u are looking into getting and see what can be done. I cant help much with the aftermarket systems out there i can only tell u how factory stuff works =)

Thanks for all the insight and quick responses!
 
Sadly I pulled the RB1 (and TERK XM radio) out of my Sebring and installed in my wife's Jeep Grand Cherokee Outland. (of course it works perfectly there)  For myself I ended up getting the go ahead to find a replacement GPS, and am going with the Panesonic AVIC-N3 w/XM Traffic & iPod adapter (ended up getting $500 off MSRP @ Cartoys).  I think I ended up with a better Nav unit, just spent way more than I intended to.  Such is the way of Cars/Boats/Computers/etc.
 
Thanks!
