A big thanks to Bob for sharing with me some of the technical specs on the radio. Armed with this, I am still unclear at this point whether or not this is going to work. Here's the current situation.
The radio unit boots up properly and I am greeted with the "Jeep" splash screen (which I would like to change to Chrysler if I ever get this working):
The system then loads the navigational data and then presents the legal disclaimer, as follows:
A map screen will correctly depict where I am currently located:
and the GPS information shows that it is tracking the satelites properly:
However, when I try to save my current position or enter a new destination to navigate to I get this error screen:
I tried swaping in the spare navigation disk with no change in condition.
As mentioned above, the PCI cable that went to my original radio has two leads, versus the new style which has only one. I tried grounding the PCI lead that wasn't being converted to the new wiring harness and it caused the "ABS" warning light to come on in the dash. The same thing happened when grounding the other PCI lead.
Here's the things that I am unsure of at this point:
1. Does the RB1 require communication with the PCI bus in order to function?
2. Is the PCI bus in a 1999 Chrysler Town & Country Limited compatible with the 2002+ PCI bus?
3. Is there a way to convert the PCI signals to a format that the RB1 will recognize and allow the unit to navigate?
I feel like I am so close, and yet so far. Any words of advise or helpful tips would be greatly appreciated.
