2015 RC F ...I pulled my map SD card to check some numbers on it ..put it back in the car and now it wants to check data forever... How long will it take .. or is it something I else I need to do...

 

If you pulled it out while the ignition was on, you probably corrupted it. When I upgraded my maps card, that checking data part only took a few seconds. Only other time I've seen that was after the battery was disconnected for a few hours while I was doing spark plugs.

 

Put the SD card back in and the map lit up....so all is good....👍🙏🏎️Thx for your input ...
