Hi Grzegorz!
Yes, it is a learning process...

. I learn new things every day...and sometimes I also make mistakes...
There were some very minor change needed to install the 605DB, and 605DC, but the chages were very negligable (the G-14/AS set-up was almost identical), and for sure not enough to warrant a second data plate.
The 2nd plate was not on all G-10's, remember...
I did have the thought of a DB or DC installation...but that also would not make sense to me

.
The search goes on!!!
