I recently retrofitted an RNS 310 to my 2014 passat. I need to update the firmware from 0212 to 0357 to get the phone function working properly. I also have the V9 maps on SD Card. In my old car I had the same radio and I didn't need to have the SD Card plugged in for the maps to work.

Will I be able to upload the nav maps from the sd card into the internal storage of the radio when i update the firmware or does the sd card with nav maps have to remain in the slot? (I use the sd slot quite a bit for listening to music)
