Yes these are all good answers. And yes I let the battery get low. And you
change the lithium battery while it's hooked up to external supply. But
no I don't use the GPS_NAV display so the voltage doesn't show all the
time. And it will be less cost if I ship through the post office. And no
offense to the vendors.

In this age of computers and rising fuel costs and shipping costs plus
insurance, isn't it possible to make better use of technology and provide
for security sealing by computer communication? We transfer money
electronically don't we? A lot of people have done electronic payments
right? You can give control of your PC to someone over the internet and
they can run a software program on their computer to load a device hooked
up to your computer. And so me average joe doesn't have the key program
to cheat (like I really want to anyway). I know this communication is
possible because I've done it.

So why is it not possible to hook up the GPS unit to the PC connected to
the internet, connect with the key master and load the serial #?

You can still pay the $20 or $40 dollar cost to the proprieter with paypal
or visa and both parties are happy.

I guess I still have to support Brown Company anyway. Thanks for the
discussion.

Hi,

Yes, it is possible to change the backup battery without breaking the
seal. Just keep the unit powered with 12V power while replacing the
backup
battery.

The customer that started this thread had the backup battery get too
low

and die before it was replaced. The unit then had a security failure
and
needs re-sealing.

Can't you change the internal battery before it gets real low without

breaking the seal?

Inquiring minds want to know.

Exact cost for 1 day turnaround by Gary at NK the week before last
was
$130 including memory battery , calibration chart,and next day return
delivery.
My experience is that this is excellent service for a very fair
price.
Certainly not the "hundreds of dollars" you seem to anticipate.

The old Cambridge DOS program for the PC reads the voltage of the
backup

battery. The Cambridge Nav head also shows the backup voltage upon
power-up.
It pay to obsesrve this from time to time.
