no. you can go straight to this update.
Did you read my instructions about editing cardinfo.cif for f10,f20,f920? If you have the right cardinfo.cif for your unit, then it will ask you to upgrade as soon as you insert the update sd card
Hi. yes i did the editing i found the long "code" (KMQ..... with X07.......) in the file and replace it with the one u wrote to use for EU version F10BT, but when i use the SD card and start the car i get an gray sd icon, but i will try another one to see if its the SD card, in another thread i have tryed tha same with the 210FM, and here i can see the SD card, but its not starting automatic, (thats another sd card) so i will try that card.
My firmware is 2.004 atm. so i say i can skip CNSD-210FM and just go ahead with the CNSD-310FM without updating the firmware to a higher version, before updating with CNSD-310FM..
