Nuvi 660 SW Version Question

I don't believe the 660 has had an update yet that prevents a rollback. I believe that "feature" is specific to the 7xx series, and the question has been posed about new updates for other models.

My .02....

A few weeks ago I was speaking to garmin regarding an RMA I had going on with my 660..

When I got the new unit..I had to update the maps so I was forced to 4.60

I asked specifically about rolling back firmware on the 660.. As well as bluetooth.
Unsure, the CR (sounded cute! ) put me on hold to confirm my question with a 'senior tech' of sorts..something like that.
When she returned she confidently told me that the 660 can be rolled back. It does not share the restrictions with the 7xx nuvis..

I can also confirm that I had no problem rolling back the BT 3.1 to 2.4. (Doing trouble shooting with the Blackberry).
I may roll back soon to 4.50 to test for what I'm looking for. I dont expect to have any problems....I hope.

Take it for what its worth. I havent heard of anybody else rolling back off 4.60

Thank you all! I believe I'll let my 660 rock into the latest version,

Why? What is not working the way you want? There are lots of bad things that can happen that you can't undue with a rollback.

How is a rollback done?

You just run the previous firmware update file with your GPS unit connected to your computer.

If you don't have it saved on your computer, you can get most of them from this site.

I would like to know the step by step procedure of rolling back to earlier version if and when ver. 4.60 misbehave

Download from the site listed above.(Model/version)
Hook GPS up to computer.
Run the executable.
Follow prompts.
Grab a beer.
Enjoy beer.
Reboot nuvi
Have another beer.

I think that about covers it.

I Do appreciate the help. I did end up doing a rollback after installing 4.60, the overlay in 3D was all amiss unless I set it to North instead of 3D. Actually it didn't fix it all with the frist rollback, so I ran a second. All is well now. sv

What version did you load?

And..if you can...keep us updated on the operation.
If you find something amiss down the road, we would be ...interested.

I went to 4.50, it actually was not what I had before because the GUI on the 3D pulldown was different than I remember. I also downloaded some extras, car colors, a bike or two, and Jack's voice. I'm not sure if that caused me problems on the first rollback, but when I elected to use one of the new car after seeing my GPS again working in 3D with "More" detail in the map, my home area map had me in blank space with no road, and pointing me into no-man's land. I decided to do the second install of 4.50 and take the results if good, and it was so I quit tinkering with add-ons. I'll take it on the road in a few minutes and see how it works traveling.

I wondered something during these trials. if you were to copy the entire GPS files and folders to the HDD while working perfectly, then totally delete the files and folders inside the Nuvi, then replace them again with the stored data, would it be as perfect, or possibly cause a ton of grief? I didn't have the nerve to try that deal. If I really wanted to play further, I'd rollback to an even earlier version(s), but my opinion right now is that it is working, so I will leave it alone for now.

If the total copy of the original files onto the HDD is safe, I still have those. Any opinions about that test? tia sv

PS Are there people with specific issues for me to watch for? That would be good to know when I do the road test.

What you asked about would work fine, but it wouldn't provide a rollback of a firmware update. Firmware files are not viewable or capable of being copied.

Your backup would protect you from the occasional loss of files that occur during some updates (maps, unlock code files, voices, etc).

I kinda suspected something else might be required. To update on the travel test today, all was very good. There was a traffic update which occurred during the install into the cradle, don't know what difference it made if any but the whole system worked fine. I bluetooth my phone and that was right on like before. I'll leave this sucker alone for awhile! sv

When you say 'right on like before' what was the problem?

The reason I'm lookin to rolling back to 4.50 is because with 4.60 a call using bluetooth would garble after a few minutes.
It seems as if the processor was being overly taxed.
With 4.50 it worked like a charm everytime.

The garbling was not due to a poor cell connection. I was able to switch to the blackberry's(7520) speaker phone and the connection was fine....
