I have a Nuvi 650, which cannot start up now
It happens after my wife unplugs the device from my laptop halfway through copying the new maps.
I have tried the hard reset - clearing all user data - but still the same problem.
The device will just hang on the start up screen where it says loading maps...

Can someone help me please.. what should i do next

The guy who wrote the program is a genious.

in the pre boot mode MAPSOURCE DOES NOT send any maps, cause of device capabilites limited in this mode.

You have to start your device to have disks. OK.
The main idea - to start the device and delete these gmapsupp.img wrong file. (or another "bad map" file img). How to do it if the unit does not start?

Let's use the updater, PRE-BOOT mode and some modified self-made service firmware.
http://e-trex.info/fw/nuvi/610_660/fw_n ... isible.rar

Unpack this file and start the device in the pre-boot mode. (hold the POWER button until the LOADER message appears)
Attach the device usb.
Run updater and select nuvi.
Click ok and proceed. Agree with updater if any additional messages appeared.
If LOADER appeared on the screen you may release POWER button and wait until unit flashed.

After success flashing unit restarts. (if you used WebUpdater before - gupdate.gcd needs to be deleted too! because of unit automatic firmware update after boot if this file exists, now it is no need in it, we will made it manually)
Now unit should boot! And there is only basemap shown (no gmapsupp, no gmapprom, gmapprom1 visible).
And now you can attach it as a Mass Storage Device and DELETE wrong gmapsupp (or whatever you need).
Then you need to make flash for usual firmware for unit. I prefer usual firmware loaded in PRE-BOOT mode, I hate gupdate.gcd

So, download the file
http://e-trex.info/fw/nuvi/610_660/fw_n ... n_v350.rar
and use it as I described above.
Now your nuvi is fully operational and have no "bad maps".

I made the service firmware manually and tested it successfuly today on the broken nuvi. It works.

Be free to copy this content to other forums, it really can help people.

The main idea to create restoring file is to rename texts like "gmapsupp" to something strange "umapsupp" in the firmware code. So, unit starts, searches umapsupp.img and does not find it - we are lucky, we need it

Hi every sifus here, Í'm noob and very new to GPS Navigator. Just a moments ago I just bought a Nuvi650 from another msm member, would like to ask sifus here if any one of you know that Nuvi 650 can't locate a destination by road name search? If I want to enable it, what I should do about it?

Thank you if any sifus here can enlighten me with an answer.

it's a January 2008 map, i do heard that i need to update it to the latest April 2008 map only i can use the road-name search? Is that true?

Thanks sifus...
