P.S. what is TMC?
The Carminat system is based on the VDO MS5000. You can download a manual for that system using the following link.

It's close enough to be helpful.

Regarding your problem it seems like you have lost your GPS aerial input. This could be the GPS receiver (in the glove box), the wiring (unlikely) or the shark fin aerial itself (most likely).

You can check if the system is receiving GPS data by ...

CODE -> 4112

This should show more that 2 satellites.

TMC, by the way, stands for Traffic Message Channel and provides dynamic updates to the navigation based on traffic reports. It's transmitted over the Classic FM radio frequencies via a dedicated FM tuner built into the GPS dash mounted controller. (you don't need to have your radio tuned to Classic!)
If the TMC icon on the display is grey then you need a map CD update to get it to work. If it's red then you have a problem with the receiver. If it's green or shows TMC_INFO in green then it's already working.
You can get TMC enabled disks from Renault for £130 or from ebay for about £50.
