I found the load sequence was wrong and it would never work, so I had written 
a script way back when fc7 was freshly installed to unload all the modules, 
and reload them in the correct order, and that is run from my rc.local 
script.  Generally, once the script has been run, it Just Works(TM) but I 
think I'd disabled that when the kernel got nuked, but running it by hand 
gave errors now because of module renaming.

Yup, all that.  The photo's FWIW, need a net connection as you move otherwise 
it will drive you bonkers bitching about the dead network.  I had a heck of a 
time figuring that out as the error message itself isn't exactly helpfull as 
to what option needs that live connection.

I did that, also disabled the map follows gps button, but if the gps is turned 
on and delivering data, you are surely screwed, the map orientation requester 
is helpless.  This was V-19 of roadnav.  Still fresh.

I would have had the missus in the shotgun seat do that, but she doesn't 
travel those kinds of distances at all well, so I didn't take her.  Then 
caught a small amount of hell when I got back cuz I didn't even ask & I can't 
recall one way or the other if I did.  I'd get me another missus, but I've 
got 19 years in training this one on 12-2, 3 weeks on down the calendar.  So 
far she has been a 'keeper' :)

And in my present mood, sad, I forgot to say thank you, so thank you very much 

Cheers, Gene
