Dear fellow members,

I'm currently trying to update the maps of my TomTom Carminat to the latest possible version. I have the 25920 4655R.
TomTom website states that it should work when installing TomTom HOME and that the SD should be recognized. However, this doesn't work.
I have a built-in navigation system, so I can't connect the device to my PC to let it be recognized by the program itself.

How can I solve this issue? I just want to update the SD card and put it back into my built-in navigation device...

Thanks in advance for helping me out on this.
P.S.: It's a Renault Megane, if this helps you any further.
