French Helicopter upgrades

Can anyone help me with the following French upgrades that are currently ongoing:

1) French EC725 Cougar
2) French AS-565 Panther
3) French SA330B Puma

I am trying to understand whether the following are being upgraded or not in each case?

1) Navigation system.
2) Radar Warning Receiver (RWR)
3) Radar

My guess at the moment is that in all three cases all systems are being upgraded to the following configuration.

1) Sextant NADIR Mk 2 Navigation system.
2) Sherloc Radar Warning Receiver (RWR)
3) Bendix 1500b Radar

OR they are getting the:

TDS-H
SPS-H
MWS-20

But that still leaves the radar, which confuses me.

Any comments? Anyone?
