No mention made of added support for a secondary mapset on the SD Card as was reported with the previous (pulled) v5.20. Maybe they forgot. I'm staying away since v4.90 works fine for me.
Change History
Changes made from version 4.90 to 5.30:
Important: This software update will restore user settings to default.
Fixed an error that sometimes caused units to shut down after upgrading software.

Not the same
Another interesting observation is that when you compare both, the file sizes are different.
As an example for the 7x0 series, version 490 GCD file is 8.62mo whereas the 490 exe file on gawisp.com (Perry) is 4.84mo. Why the difference if both are the same
All I can say for certain is that they are not both the same. The .exe file has an installer package included which may unpack the files as well as contain information on where to (or how to) install it.
The .gcd file might just contain the firmware and a short header file with location info.
In any case, the extensions are different so the files are different.
thanks
This from the Nuvi 750 manual:
"If the touch screen is not responding properly, calibrate the touch screen. Turn the unit off then back on. Slide the power key to the right (lock). Hold your finger on the screen for about 30 seconds until the calibrate screen appears. Follow the on-screen instructions."
Works for my 750 running v5.30
Yes, that worked.
Sliding the power key to the locked position is important in the procedure.
Thanks,
Howard
I do the same.
Agreed

Back to 4.9
Well, I finally had the lockup issue -- I must have hit that 500 mile limit while on my drive to a Midsommar Fest this weekend -- so back to 4.9 I go!
It's amazing how much more responsive 4.90 is over 5.30!
