Need Help with my Navman 8120

[rigormortis]

Hi folks:
Bought my Navman 8120 in 2009 and it has worked flawlessly from Oregon to Chile to Thailand. Just bought a new C-map wide chart to get me to Brazil and it will not work on Navman. All my other (5) megawide charts do work fine. Did a factory reset and no joy with new chip (S card type).
Jeppesen is now telling me I may need a software upgrade to the 8120.
If I can get the software upgrade (on my computer, I guess) how do I transfer that info to the chartplotter?
Tried phoning Navman NZ and AUS but they don't work on weekends and their emails do not work. I know Navman has been sold since 2009 (more than once?)
Of course, the s-card chip may be faulty but hesitate to mail it back to USA until I exhausted any alternatives.
Any advice appreciated.
Pete

Hi there

I have a Navman 8120 Chart Plotter and am struggling to get assistance from Navman/Navico. I would like to make contact with anybody who has one. I need a small switch but am unable to identify the correct value. All I need is a photo of the part marked Q5 - photo attached. If someone can take a photo I will be able to identify the value and purchase one from the local electronics shop. Any help would be appreciated.
