RT6 RNEG 2.8 Satnav/Radio

[skycar]

Hi to all here,
I recently took my car in for a service and replace the "Doser" 2015 C5 2.0 HDI and when it was ready to pick up the RT6 RNEG 2.8 Satnav/Radio will not come to life.
It just keeps cycling over every 10-15 seconds trying to load a CD.
The fuses are good, no light up of the display, just repetitive cycling of the CD player trying to load and the warning system going off on every engine start up.

I have read several write ups about this issue and most people are saying that the SD memory card needs to be upgraded from 8Gb to 16GB and download new maps (2.86) and then somehow partion these files and load onto a USB memory stick. Then boot up and download files back into the radio.
That is a monster for me to write let alone pretend I know what I am talking about.

Can anyone help or direct me to where I can get that help please?
Is there anyone here that can do this for me and I pay you?
I live in Brisbane, Australia
Thanks for nay info,
regards Roger.

It may be the start of the internal MicroSD card failing - each case is different, but you may want to try reinstalling the maps first.
