I'm new to can bus world but have been a electronic hobbyist for many years.
I have a project car that I've put a 2005 Durango 5.7 hemi in a 1966 Dodge coronet .
I'm using a standalone engine/transmission harness and all that is working well.
I would like to use the REC radio in the Coronet so I did google searches over the last couple of weeks, bought a usb-can dongle and wired up the radio on the bench.
My understanding is the instrument cluster ( it was already pulled from the donor Durango when I got it

Currently here is where I am at so far.
When power is applied to the radio the 6 disc cd changer cycles and if you punch the load button while its cycling the changer the lcd screen turns on with the cd slot #s displayed and you can load and unload cds into the unit .
I hooked the can-usb dongle up and I tried all the power up codes I could find, they all behave the same, in fact if I send any can message from the usb dongle the knobs and button lights go on as long as I keep repeating the send. but the radio on/off button has no effect and the screen never turns on.
The can usb dongle app shows I'm receiving the following data from the radio in response to sending from the can-usb note: it does this with any id/message sent to the radio.
NO Direction Time Scale Frame Type Frame Format Frame ID Length Data
0 Send 02:46:36:968 Data frame Standard frame 00000415 8 fd 16 3f ff ff ff ff ff
1 Receive 02:46:37:083 Data frame Standard frame 00000416 8 fe 16 3f ff ff ff ff ff <repeats 15x>
96 Receive 02:46:42:402 Data frame Standard frame 0000009f 8 07 20 00 00 ff ff ff cf <repeats 70x>
My question is there some follow on message that has to be transmitted to the radio following the power on message ?
and the nav dvd is missing , will that stop the radio from turning on ?
Any help would be appreciated
Thanks for looking,
Robert
