Bit of background for you the upgrade for the denon link 3 was,
ESS 6609-B,
MAKEDAY 413D
DRV 030825,
SYS 6767-5
DSP 6770,
C20041028
CD1 VER.6609-B. CD2 VER,6767-5. CD3 VER,ER1028.
For this upgrade you did not have to initialize,according to the denon service information sheet I have, As you can see the ver, type forCD2/3 has not changed but that's not to say the data on the latest download has not,Also the instructions for initializing has moved to after download to befor/after, so if in doubt just do everything, If cd2/3 data is the same the dvd player will overwrite, hope this helps and if anyone knows different please correct this, Brian.
