This will all depend on...

This will all depend on the method one uses to perform the downgrade and the bugs that will be reintroduced into the unit from the previous version.

Depending

Depending on the model your using and the firmware you are downloading from and to you could loss functionality that can't be recovered. For example, some users lost Bluetooth when downgrading the 7xx series past a certain version. Once lost nothing could reestablish the bluetooth function on these units.

So be careful when considering a downgrade.

Just out of curiosity why would you want to roll back to older F/W?

Some units it is not possible. For example, older 765T's can be downgraded from the current V3.90 firmware. Newer ones use a newer processor board that specifically requires the newer firmware. Attempting to downgrade to an earlier version results in a "white screen" display. You then have to go through a recovery process to install the newer version again.

Rollback (firmware, not prices)

I rolled my 750 back to 4.8 twice. Both times I tried the update my unit started locking up. Something is wrong with 4.9.

My 770 started locking up

with 4.9
But it's only locked up twice. Using map mode (non routed) about an hour into a trip it siezed up.
Since then it hasn't siezed up in map mode again.

I downgraded my 765T

Because the latest revision (3.90 I think) introduced a slow typing problem into the onscreen keyboard while typing in search data on custom POI's. Something I use a lot. Had no issues downgrading, all other GPS functions (BT, MP3, etc) are fine.

Stop

I have owned alot of electronic equipment in my lifetime but have never experienced or seen such lack of quality in a device. If Garmin can't make a device that works right the first time I think they should possibly stop making GPS's. Every unit and I mean every unit seems to have some sort of problem. If there updates had improvements, that would be great but it seems they are always trying to fix something and the fix screws up other things that were working. Just look at all the posts at the POI factory. Should we have to go through all the agony of trying to make something work. Is it the same issue with Magellan and Tom Tom? Do they have as many problems? I don't know.....

It's ridiculous and totally unacceptable. As you've stated, multiple problems on multiple units. A good example is the 7x5 series. December 18th 2009 they come out with firmware 3.90

Users shortly afterwards point out the numerous problems encountered. Result: 6 months later Garmin still hasn't come out with a fix.

What do the users do ? They learn how to rollback to an earlier firmware and patiently wait, hope and pray that Garmin resolves these problems and not create a worse one with the next upgrade.

They've encountered problems on other models in the past, and these same problems appear on a different model a few months later ! HELLOOOOOO

I agree nothing in life is perfect but concerning Garmin and their automotive lineup, theirs definitely a major problem.

Garmin doesn't make GPS's, they sell them. The unit is made overseas, my 750 was made in Taiwan, maybe to Garmin's specs maybe not. There are a lot of companies in Asia that will design, manufacture and brand the product for you, you just pay the bill. It is beginning to look like Garmin can't control the quality of the units they sell. If Garmin does own and manage the factories that produce their units then they consider the GPS market to be a flash-in-the-pan and not worth the cost of supplying a quality product.

Investigate first

You all know the old adage; measure twice, cut once. I try to avoid "upgraded" software and firmware and investigate what the new "upgrade" will do. For instance, I still use Windows Office 2000 because I don't necessarily need all the new bells and whistles....

I agree, most upgrades are unneeded but sometimes you are forced to upgrade. In my case I had a problem with stuttering (the Garmin, not me) so I upgraded to a version that fixed the stutter but broke something else. V 4.9 is supposed to fix a problem with the low battery level indicator/warning. I don't use mine on the battery much so that fix isn't important to me but a working unit is so I rolled back to 4.8 and I'll stay with that version until one is released that works.

Agree

Absolutely. I was a software developer in my former life and learned way back with DOS 3.0 to be very careful about upgrading systems. Sometimes you don't have a choice but if you do, give it some serious thought. There is a reason they call it the "bleeding edge".

Go to this site and download the firmware you need:

http://www.gawisp.com/perry/nuvi/

Hook up your GPS to your computer and run the file you downloaded. That will do it.
