D100 - AP74 - AVMAP 4

[00G05]

Hello.
Can someone help me with the settings on my AVMAP/D100/AP74?
Last weekend my AVMAP 4 gps struggled with a black out, I think because battery failure .(factory mode)
When I want to go flying I noticed that there was no GPS signal in he D100 HSI, So not possible to activate TRK/NAV ont the AP74.
I looked at the bound rate in the AVMAP and D100 and put it both on 9600 , after that I can Set the TRK butt still no NAV function.
They told me its something whit the NMEA ?
MY setting for the moment in the NMEA is RMC,RMB,GGA and PROCESED. Do I need to activate more or otherwise?
Thanks for your help in advance.
Greeting Danny.

Try also Static Navigation= ON, External NMEA=ON (default is OFF), & BOD. Page 91 of the Avmap manual gives info re GPS fix & page 51 gives info re current status of available satellites - if that's all good then I'd also make sure the 2.5mm output cable is fully plugged in & that its also not 'damaged' - a multimeter would help with that.
