updating rs 130 gps firmware

[AJS]

I have a sailboat with all raymarine components with 2 e127's 1 70 instruments,p 70 autopilot with spx computer, ais 650,sr6 weather,hd color digital radar,itc 5,stng converter.All software has been updated to the latest versions except the gps rs 130.I have downloaded the update files to 2 separate micro sd cards at the root level.The bootloader and autorun files are on the first card and the 3.03 package and autorun files are on the second.When i put the bootloader in the mfd and turn it on it simply starts up and does not recognize the card as a software update and simply starts normally.If i go to the maintainence menu and look for devices the rs 130 is recognized and listed with its current software version.
I also tried doing this with wifi and the system states that no software update is available even though the rs 130 is on the device list with the previous 2.20 version.
Should i try the 3.03 pkg without doing the bootloader ?
The gps is functioning normally as configured presently
Many thanks
