Here is my effort on coding F48 from stereo to Hifi. Hope it helps if someone interested.
I know that in US you have hifi standard. What I am planning to do is code my F48 from stereo to hifi.
I have already and BMW ENET cable and E-sys software etc installed and running.
First I will add “676” to FA and write.
My question is : do I need to code any ECUs after that? Or is it done automatically when adding option 676 to FA? I saw people coding “FRM” and “CAS”?
I have changed the hardware.
It should be compatible with low level signal.
Finally, I adapted a step by step. Maybe it will help others if it is correct..
add 676 to VO
————————————
– Use F048 to connect with E-Sys Launcher
– “Connect” icon
– Selecting F056 (do not select “_DIRECT” option) as target when starting connection to car. (Connection via VIN)
– Expert Mode > Coding (left pane)
– “Read” button (top window)
– Right-click FA > Activate FA
– Save (name it as you want)
– Edit
– Expand to see “SALAPA Element”
– Add “676” in bottom window (alphabetical order)
– Right-click FA > Calculate FP (check no errors)
– save with top right corner icon
– back to previous screen with green arrow (top left)
– Re-save
– Expert Mode > VCM
– In File tab (bottom window), select saved XML just before
– In VCM Master tab, “Write FA FP” Button
code modules
————————————
– (Connect)
– (Read FA)
– (Activate FA)
– Read (ECU) Button
– Right-Click on ECU “hu_entrynav”
– Select CODE
Coding is ok, but you didn’t need to wait 10-15 minutes – after reboot of head unit, the parameters are coded.
I confirm ECU is “HU_ENTRYNAV”
Coding worked without any error. I checked that option 676 is in FA and that “hifi” value replaced “stereo” everywhere in HU_ENTRYNAV FDL.
