Hi i was wondering

are there some SD cards that don't work in our units and some that do or will our x series or should i say our x930bt only read some sd cards i know its got to be a Mini or Micro SD card

but i have read somewhere that sometimes units won't register or reconizie some brands like PNY at times is this true

 

also how often do new updates for our x series come out does pioneer put out new map updates yearly or is it more like every other year

also how do we get them do you have to go online and buy them and load them onto a sd card and save them or

do we have to just go out and buy or order a map and they send us a SD card with it on there

 

also if for some reason the maps get erased will pioneer send us a SD card with atleast the map that was up to date at the time of purchase or do we still have no choice but to buy one ?
