L-Nav v 5.8 EPROM

Hi Steve,
I powered up my L-Nav and the home page showed the version, but I forgot what it was? Sorry!
I took a picture with power on, but I can’t remember how to find it in my phone?
You could ask my babysitter, but I’ve forgotten her name, Patricia, maybe?
The doctor told me to start thinking about not driving anymore............told him that was a big relief, Doc, I was afraid you were going to tell me to stop flying!
JJ..........turning 86 next month!

Locating a hidden batch of NOS of the desired EPROM version seems highly unlikely. Did you check with Gary Kammerer who supports Cambridge products?

If not the only choice seems to be to find someone with an L-NAV with V5.8 and;

1) Buy it.
2) Borrow it, remove the EPROM, and find out how to make copies of it. Not really a do-it-yourself kind of activity but there are services on the web that will make the copies for you. FYI when shipping the EPROM wrap it in tin foil to protect it from static damage.

Best of luck.
