Of course you know that very much more than me! But I'm in doubt; in that case I always reinstall the firmware, never defrag and optimize because I believed that not serve to the Garmin data format... In last case defrag and optimize? Can Giomen or someone explain it better, please!Quote:

The GMA and UNL files 'tie' the map to a certain unit, or indeed several units which are entitled to the map thus allowing the entire map or certain portions of it to be loaded from your PC to the qualifying unit via MapInstall. As you've found, without both sets of files the map would be useless on your unit [unless then unlocked with an unlocker e.g. gimgunlock to remove the GMA proctection]. The unl and gma files actually serve quite different functions, but their lack results in effectively the same result.

I'm of this opinion Pungente: If hard reset/clear NV/reinstall fw/correct reformat doesn't resolve the problem then, and only then as an absolute last resort, go further and defrag etc. This is because imo defraging flash drives does not have the same value as defragging mechanical hard disc drives because the two types work quite differently. Defragging a HDD can only benefit it because by rearranging the data so it is more easily found and thus reduces the time involved in seek heads jumping hither and yon to find it. Flash drives actually place data in different places quite intentionally to enable 'wear levelling' to occur so that as much of the available space is used as often as possible. Unnecessary reformatting 'uses up' this wear levelling and hence the remaining effective life of the drive. Defragging probably has a similar and even more dramatic effect. I believe that's why Giomen added the emphatic 'Be careful!'.Quote:

This is an interesting subject, however if it continues here I'll spin it off to another thread. I'm not an expert in this field and the above is a layman's view and opinion.
Defragmentation and optimization is not good for often use on Flash Drive like Nuvi and other device. At most case these activities have a zero effect. But you can try its if your Nuvi drive looks like New Year confetti on the holiday table. The best way to do backup, clear memory and then put it back on Nuvi even without format. It is refresh allocation table and sometimes is more speedy than defragmentation and optimization.Quote:

In any case then the data is storage as solid piece it is very good for any system stability and data recovery. I am old school specialist and my teachers said to me if you divide data on many piece and hide it in many place nobody can easy recover it.
Hello,
should I upload the .sid files of the 34xx on my nuvi 2455?
Are these files necessary to use instasearch?
You can easily check it looking at you Nuvi files or at Garmindevice.xml file in your device in Garmin folder.
You should have all flles listing and paths.
Older files names begin with the same digits.New ones increase by 10 per version.
@ ioannis0
It's LOG for your 2455 (EU Full):
Spoiler: DATALOG
@jimmy
I have downloaded the map from this topic and I'm asking if the .sid files from the first post are compatible or if they are useless with the nuvi 2455.
@Roger
Where did you get this log from? This is for the 2015.10 map version but if it's correct I should download the .sid files from the first post and use them with the 2014.40 map.
Thank you.
Yes,sorry...my great mistake :)Quote:

@ioannis0
Your question was answered by jimmy and yes, your 2455 does use *.sid files. As said, look to the unit's GarminDevice.xml found in Garmin folder. The previous map version files would be -10, -20, -30 etc depending on the version, 2014.30, 2014.20, 2014.10 etc. The next [and current] would be +10 for 2015.10 i.e. D3427120A.sid; D3176140A.sid;D3175140A.sid and D3414130A.sid. The files are maps version specific so need to be changed when you update the map.
Files are stored in .System/SID folder and are for traffic trends ,instaSearch , instaAdresses & POIs and FastRouting. More info: [Only registered and activated users can see links. Click Here To Register...].
2015.10 was released a couple of weeks back, but we've previously neglected to close this thread. If further discussion is necessary please post in the new map thread: [Only registered and activated users can see links. Click Here To Register...].
