Will my 760 boot faster if I get rid of all of the POI's I don't use?

Not sure how you can get rid of the POI that come with the unit they are part of the Maps files. For the Most part the POI on the Unit are pretty good. I dont see how it would Boot faster, as the POI do not load as you boot up...they only load during a search. My 660 boots up in a few seconds, I can not think of any way to make it much faster.

You cannot delete the built in POIs.

The real question is why is the boot time a problem? Do you have the latest updates? Because if you do the unit should boot within 30 seconds.

If you are really that concerned about the boot time then just leave your unit on.

You cannot remove the built-in POIs. If you use an auto or motorcycle to make your deliveries, why don't you just leave the unit on in battery mode between trips? Rebooting would be quite a pain.

Edit: GadgetGuy beat me to the suggestion.

Keeping firmware updated is always the best option

My unit started to boot slower than Microsoft XP after I installed an update. I reinstaled and it now boots in ~20sec, but thats up from the 16 sec right after the reinstall.

When I select yes to leave on it behaves differently when I start to drive. I doesn't start the route the same and has to reroute right away, witch can take a few blocks.This may not be a problem for a lot of you guy's, but in the city(DC) it is, and it's agrivating.

For example I used to be able to start the car(with the unit in the cradle), buckle up, and it would be ready for an address. Now after all the updates it keeps getting slower.

Do you have any MP3s on the unit or the SD card?

I keep MP3s on my SD card. Does that slow things down? Does the presence of the SD card slow things down? What else do we need to know, MM, to keep our GPSr units running lean 'n' mean?

thanks

I don't know if you're talking about software booting up or the unit not having a fix on were it is, but if it's the latter your unit may not have good "almanac" data. This data allows you to acquire satellites much faster. With new units or after updating software, I put my Nuvi in the car, outside in the driveway, turn it on and let it set there for 30 minutes before moving. This allows the unit to download almanac data without interruption. I do this on my own assumption that the firmware updates blow off this data. If nothing else it makes me feel good
Hopefully you can get a software update and give it a try.

It doesn't slow them down on the card. In fact, IMHO, that's the preferred location.

However, if you have a lot of MP3s, the unit will be slow to start up as it must read all of them at start up.

One thing that can improve the time, though is to bread them up into folders rather than having them all in a single folder.

My 770 takes longer and longer to boot as well. The satellites acquisition is also taking more and more time. I have the latest firmware update, no MP3 and I leave my modest POI's on the SD card. I have disabled the Europe map loading but without improvement.

The worrisome part is the situation appears to get worse and worse. My unit is only four-week old. Is there anything that could explain the degradation?

I got a new car not too long ago that has the iPod AUX input jack which permits me to use the iPod. I had a limited number of songs on the SD card but really don't need it any longer. I'll just remove the SD card all together.

Thanks for the tips.

Any chance of some actual data - one persons "acceptable" is another persons "way too slow"!

How long is it taking for A) booting up B) acquiring satellites.

For me the answer is 25 seconds to boot then an average of 20 seconds to acquire satellites if I start up in the same location I switched off.

Is this really about 4 seconds or am I missing something?

4 seconds could mean life or death. The OP said he is a courier. What if he's a medical courier. You know, zooming around town with vital organs in little red coolers. Can you imagine poor little Sally laying on the operating table waiting for her liver transplant. Only to be told she is going to die because the liver went bad during transit when the Garmin took too long to boot up.

We must find a solution to this problem. The fate of the world could be at stake.

Very funny, but actually I do carry tissues and organs for transplant and do have to meet commercial airline lockouts. Rest assured though the life and death part(s) is transported in rescue helicopters and such, so Garmin could never get bad press where the fate of the world is at stake.

Now, if you please, back to my reality. When I bought my 760 it didn't behave this way and I've noticed that with each update it gets slower. But beyond that my fix was to leave it on at my p/u and del leaves something to be desired. Give it a try and you may find the same issues. From a startup it starts my route(from address or favorite)fine. Now(3min later) leaving it on the unit takes several blocks to route me.

If you still can't see my pain imagine being in the District of Columbia where there are often no street signs and have many one way streets. Not going the right way right away will "drive" you crazy.

MM: I don't have any mp3s, but coincidently my first update came when I installed a few, very useful, features like red light cameras db and zip db. And that was the same time Garmin started "learning" road segment speeds.

do you want to try reverting back to an earlier version of firmware and see if that improves the situation for you?

I'll bet it might, but I ugradded to stop it from freezing at red light alerts while I was doing something else like looking at the traffic. That part works like a charm now!

But I think I may be able to compare my 760 with a new one, because I'm getting another one(on sale) for another driver.

Between all of us we have just about all the different manufactures units. I'm still hoping the NuviPhone will come to the US in my lifetime.

Okay ....sounds stupid ......or is it? I hooked up my nuvi to the comp and then went to the defrag area and choose the drive that the nuvi was on and hit enter. And waalaa ....now boots up faster and seems to route faster as well. Remember that your GPS is a small computer. You should have seen all the clutter being fixed. Just my opinion

Lots of opinions about defragging...

Just to mention a few.

The last thing you want to do is expose your Gps or SD card to un-necessary writes, defragging adds thousand of them.
Don't do it!

Bob

Do some of the new models really have a defrag function built in? If so, I wonder why?

I agree with a lot of folks here that defragging solid state memory serves no purpose, or is there something else going on that perhaps I don't understand? Does Garmin know something we don't?

(BobDee - I like your avatar )

Per Corsair's "Wear Leveling and Life Span" FAQ on their USB drives, their better flash drives are guaranteed for at least 100,000 writes per block (that's each section of the drive). These drives use "wear leveling". When referring to a 8GB drive, their data sheet says "one can write 210 GB of data to the drive each day, for ten years!". I don't think any defrag agenda will exceed this.

In addition, the speed when writing to the nuvi 350 is so slow, any possible increase of write speed is welcome. Using a program that writes ones and zeros in a 50 mb file, the write speed is .241MB/sec. Compare this to the 1.213 MB/sec write speed of an antique 128 MB USB drive.

I've defragged all of my Flash drives and have never lost one because of 'wearing it out by over-writing'. You'll probably physically lose it, or replace it with new technology, before this happens.

After reading several articles sent to me and here on POI, I admit I am wrong and I stand corrected! It helped my unit a little but I won't do it again. It all makes sense to me so .......don't defrag your GPS. You learn something new everyday they say.

Thanks to all those who sent me articles and blogs about the subject.

I was playing around with what I just read her about "push and hold speedometer". Scrolling through the various screens got me here:

Don't know if this will help anyone, but thought I'd post just in case!

Well it did it again. After either looking at the traffic page or removing my 760 from the car mount, I'm back to a 50sec boot(and freeze at "maps" from an 18sec boot after I reinstalled the 4.20 software update. It lost voice until I rebooted and then selected the English one.

So it looks like either the red light DB or the car charger removal and returning is my problem.

Any ideas?

Thanks.
