I also have an obdeleven. When trying to change bits in radio56, it won't let me make the change for fender. I also entered dev mode, it gives me the 31 not available.4. Coding this thing?
The proper coding for the unit is
16 00 04 40 00 05
40 at block 4 enables the reverse camera.
If you have Fender change block 2 to 01. If you have Dynaudio change block 2 to 05. On either you will also have to change block 3 to 00.
I used a OBDeleven and had to go to Radio-56, switch to development mode in service to change block 2.
In all aspects of coding our NA VW's consider these to be RCD-510's and you can use the same code labels in VCDS.
I disconnected the battery at installation so it "works", but it's not giving line-level output, it's trying to power the speakers, so 3 clicks up from zero volume is pretty loud.
a bit of a noob with the coding aspect, but i haven't found any other information other than yours
