Very slow start up of nüvi 265WT

**SanFrancisco** · 14th October 2017, 06:33 PM

I bought a nüvi 2xxW off eBay, which was advertised as stuck in a perpetual start up cycle. On arrival, I confirmed the defect (software missing). See video clip:

[Only registered and activated users can see links. ]

Since the ID placard at the lower side of the device was missing, there was no way yet of telling the exact model. I managed to get the device in pre-boot mode and use g7towin64 to extract the unit-ID, device model, FW version and HWID. It turned out to be a nüvi 265WT, HWID 0827.

Getting the device back into pre-boot mode and using GarminCure3.exe and Updater.exe (thanks, kunix!), I was able to flash original FW into the device. It then was able to start up normally. Although... it takes 50 seconds of staring at the Garmin splash screen before it shows "Loading Maps...". After a total of 65 seconds, the unit is fully up and running. Functionality and response time from that moment on are normal.

I restored the device to factory default, but the 65 second start up time did not get any shorter. The same time delay is experienced when connecting the unit as a mass storage device to the computer.

Besides the steps already taken, any suggestions as how to speed up the start up process? Thanks!

Edit:
The software on the device has already been updated with WebUpdater. GarminExpress does not offer any further other updates.

Check GPX folder for any files which are not matching current.gpx name.
Delete or rename extension for any img and gpi files.

Thanks for your response. The X:\Garmin\GPX folder only contains an empty Archive folder and a Current.gpx file.

The X:\Garmin\Poi folder is empty.

Edit:
I renamed gmaptz.img and gmapbmap.img to *.bak.
The (only!) detailed map is located on an SD card, which I removed from the device.
No difference in start up time.

Series 2 nuvi devices should boot up in about 10-15 seconds. Some devices will perform better if there is a detail map on the device, even a tiny one. Just a few tiles of an OSM not already covered by your SD's map might be enough to get it to boot faster.

Try checking for any bad memory blocks in diagnostic screen (press battery icon for more than 8 secs)

Sorry for the delay in my response. Other priorities popped up.

Placed a 5 kb size unlocked detailed map on the device. Made no difference. Also not when removing the SD card containing the other detailed map.

It appears RAM and ROM are both fine.

I am inclined to think the data in a particular rgn may be corrupt. After all, it takes 50 seconds until map data is being loaded. What is the device doing all that time? Probably reading rgn's. As mentioned, once the device is up and running, its operation is without any flaws or delays.

That did you keep in mind under restoring of factory default? Due to a huge time of Reset on the screen I think you did not reset device properly. Did you perform to return to default settings in menu only? Or did you make master reset with finger holding on lower left corner when turn on device?

Sorry for the long absence, guys. Have been buried under work, both professionally as well as privately.

Have not tried that yet. Obviously, will backup rgn 41 first before erasing it, as suggested by o4i.

The device was reset to factory default by pressing and holding the lower right hand corner of the screen while switching on power.
