Updating inbuilt satnav on an older car?

[Davo123]

Hi

I have just been given a renault grand scenic dynamique 2010 by a friend. I'm looking to update the built in sat nav on it. I have taken the SD card out the car but can anyone point me in the right direction of how to update the maps on it.

Google search suggests Renault site or the Tom Tom site but can anyone help with the exact place to get this?

Thanks?
