I would like to share my experience with Magellan Maestro 4040. I’ve picked it up in Costco at $299 and cannot be happier with this device. Having extensive technical background I attempted to learn more about inner workings of the device to improve my end-user experience and so far discovered a few tricks that may be helpful for some Magellan Maestro 4XXX users.
I’ve heard some people complain that after firmware upgrade or just after a period of use the Maestro slows down when searching for Zip Codes, Street Addresses, POI Names and pretty much anything else.
Note that searches for Zip Codes and Street Addresses on Maestro should be almost instant. If it takes longer than a second to find a Zip Code or a Street Address then you may want to read this post.
I believe the problem is fragmentation of map data files. I cannot be sure about fragmentation of map data files, but after a series of experiments I’m able to both slow down and speed up search speeds at will.
Please note that operations described below require some basic computer skills and wits. In any even I cannot be held responsible if you brick your device or do not achieve expected results. Any changes you make to your device are your responsibility.
How to perform clean installation of Operating System 2.36 and optimize search speeds on Magellan Maestro 4XXX
(Note that some Maestro models do not have 2.36 OS released yet.)
Also note that if you have a Magellan Maestro and running anything less that version 2.36 – you should upgrade to 2.36 if available. This will completely change your perception of the device. Nearly all whines and complains from Garmin lovers have been addressed. In fact, I did several comparison tests with NUVI 650 and I say Maestro is the bomb.
(SECTION 1)
There are a few steps you need to do before going through with this.
1. Obtain a copy of latest Magellan software/firmware update. Currently 2.36 Release 3. Note that even if you have 2.36 on your device already you might not have the latest version. In the past few months Magellan released at least 3 versions of 2.36. Go figure. Anyway, go to Magellangps.com and get it.
2. Get an SD card. 32MB will do nicely.
3. Put SD card in the device and reset it using needle in the hole below USB plug. This should create USBTRANS directory and UNIT_ID.DAT file on your SD card. Check that. If not, copy USBTRANS directory (with UNIT_ID.DAT file inside) from your Maestro’s SYS directory to SD card and reset the unit again.
4. Navigate through Maestro’s screens to make a backup of your address book and settings. Look in the manual to figure out how.
5. Make complete backup of your Maestro. I mean plug in your device to your computer via USB and copy every file and directory from SD card and Maestro device to a safe location. Pay extra attention to MAP directory. If you lose it you are screwed.
(SECTION 2)
Now it begins. Make sure you really decided to follow through with this.
1. Format your Magellan device (keep label TFAT) with FAT32 (use default allocation unit size).
2. Format your SD card. You do not need to remove your SD card from the device to format it. It will be recognized as Removable drive by your computer once Maestro is plugged in to your computer’s USB port.
3. Copy MAP directory from backup (Step 5 Section 1) to root of Maestro’s TFAT drive. Just drag the whole directory to the root of Magellan’s drive. Make sure that MAP directory is first to be copied to the device. Do not copy any other files to Magellan in parallel while copying of MAP directory is in process. This will ensure optimal map data placement and provide for lightening fast searches.
4. Examine SYS directory in your backup. Ensure that the following structure exists.
SYS directory --> USBTRANS directory --> UNIT_ID.DAT file
Do not copy any other directories or files that may exist in your backup in the next step.
5.Copy SYS directory from your backup (Step 5 Section 1) to the root of Maestro’s TFAT drive. Make sure to copy only the following: SYS directory --> USBTRANS directory --> UNIT_ID.DAT file.
6. Copy USBTRANS directory from underneath of SYS directory (from Magellan’s TFAT drive) to SD card.
7. Copy backup directory from SD backup (Step 5 Section 1) to SD card.
8. Run Magellan’s 2.36 OS update (get it on Magellan’s website) and make sure to plug in external power while doing it.
9. Once update is complete unplug USB and Device will go through a series of reboots and finally come up in brand new and untouched state. Just like you first bought it. You may wish to restore you address book and settings after setup is compete.
That’s it. I’ll try to share some more trick once I get time later.

My 4050 will not allow me to load the update via USB. I was wondering if someone could email me the files that are loaded on your SD card for the Maestro 4050. It would be greatly appreciated. Send me a message and I will send you back my email. THANKS A MILLION! |

Hello everyone,
I have read this whole post and the questain has been asked a few times but no one seem to answer it.
I have the 4250, it was bricked meaning it would load the magellan screen with the process bar that goes to 100% then just sits there, and could not connect to the computer though USB.
being new to this I found a forum that gave directions to fix this, so I did it, Well the directions this guy gave told you to update boot loader ( erase flash ), which it the wrong thing to do, I know this now, but its too late. I now have a white screen with the process bar and a system setup that has no S/N.
Now this is what I would like to know, Can the boot loader be re-flashed with a copy of one taken from a working Unit?
I have read every forum I can find and no one seems to know or they say NO, If we can erase it why cant it be re-flashed?
The closes I have have come is with DiskRW, it does see this Loader, but I cant save it to sd card there is no keypad to type where I want it saved to, and the browse (...) doesnt bring up a menu either.
Any thoughts would be helpful.
BTW I do have a couple of working 4250's I can get the flash image from, just need to know how. |

Is there a way to see lat/log of saved locations? I carried my 4250 on several long hikes in N. Ga and I'd like to put the trail landmarks on Google terrain maps. I filed a ticket with Magellan. They politely told me that was not a feature off the 4250 and that no utilities were available. I've looked at two hidden menus, neither appeared to have what I'm looking for. Alternative is to accesorize with pen and note pad.

I need the full directory tree listing of the TFAT Volume too, my Maestro 4040 files were corrupted and I was able to recover them, but they are in folders called LOSTDIR01 etc. so I need to know where they go. Any help? thanks! |

So it boots and the interface comes up, but anything that needs the map/poi files just gives a screen about inserting an SD card with the map files on it. Fine, I understand that, and hopefully I can find someone with a 4000 who can send me the map files, and hopefully they aren't locked to a particular serial number.
However, what does worry me is that the serial number that it displays is 000000... I restored the UNIT_ID.DAT file (to \SYS\USBTRANS\ directory), is there something else I should be doing? Or is that a side-effect of not loading the map files? |

Also, I'm still looking for anyone who can supply me with the map files for the 4000, please contact me: sep -> shout . net (corrected with the correct e-mail address);
Update: I managed to get around the security and run the update, so as far as I know the only thing I'm missing now are the map files, the unit runs normally up until the point it needs them. Thanks if you can help! |

Ok, so with a wiped unit, first install WinCE (by putting the correct winceimg.bin and winceimg.cks from the upgrade onto an SD card, getting into the boot menu, and selecting WINCE upgrade by SD/MMC) (but what's the difference between the two, one with and one without (Format), does that just do a wipe just before updating it?); then restart the device which will bring up enough of the OS to allow you to connect it to USB cable to transfer the MAP directory and \SYS\USBTRANS\UNIT_ID.DAT, then run the update to load the rest of the files ...?
There's WINCE by USB option in the boot menu as well; I believe a windows utility called dnw can talk to that; anyone know of any documentation on the protocol used by that for us non-Windows people (Linux/Unix/OSX), and/or compilable source code? Otherwise I have to wait until the card reader I ordered from eBay gets here (as the only card reader I had was the GPS unit itself).
On Mac OSX (before I bricked my unit by accidentally selecting the Format Flash, which does NOT have any confirmation step!!), the two "drives" (the internal and the SD card) did show up as mass storage devices, but had I/O errors attempting to read from them; I'm wondering if the Windows device drivers send some magic command to unlock them or something, as they appear to be totally standard USB storage devices otherwise. Anyway, that's why I don't have a backup of the MAP files, so I need to find someone who has another 4000 unit to get the map/POI files from. Any help with that would be appreciated. Or, if map update that is supposedly coming soon would supply all of the MAP/POI/AAA files, I suppose I can wait until then if no one can supply them to me (I'd most likely have gone for the map upgrade anyway).
BTW, when the unit is bricked, to get to the boot menu is actually easier - with no SD card inserted, turn the unit on by pressing the power button for two seconds (mine BRIEFLY flashes the screen gray, then goes back to black, no real way then to tell if it is on or off); then press the reset button until the screen goes blue and the boot menu comes up. No need to do both simultaneously, when it fails to boot normally it just sits waiting for the reset button. If the SD card is inserted, it instead appears to try to boot off of it, but doesn't say what file it is looking for (SD card boot; Please wait...; Waiting!!; BOOTSEC is in Sector 243!!; MountDisk SUCCESS !; open file failed!; ERROR happened! Put image file into SD!). I love the error messages, e.g. "card not exist!"...
I'm totally amazed that there's very little I could find on the net about dnw, the UTOOL boot loader, or the BinFS format (there's some, but no source code that I could find for manipulating them); hasn't anyone written some source code for playing around with this stuff instead of relying on opaque tools that only run under Windows? I'd try writing a USB utility for OSX if I knew what protocol it used (I'm delving into IOKit and USB stuff for something else anyway), and such a utility could probably be easily ported to Linux as well, just the direct USB access part would need to be different.
I couldn't even figure out exactly what checksum the winceimg.cks file is using, vague references to WINHEX, perhaps CRC32, but at least one version of CRC32 (e.g. BSD cksum -o 3) doesn't seem to match on the raw .bin file (with the last 4 bytes stripped off, which contains the checksum). E.g. in the update, the winceimg.bin/cks files from COPY_GROUP_2, file size is 6171620, checksum is 0x24C7BF1E; cksum (default) gives 0xBF5DD0C, cksum -o 3 gives 0xD11D50C8 (cksum gives decimal values, those are the hex equivalents).
I looked at the Setup.mgup file, which appears to be a command script of sorts for doing the update; anyone know what the file format is, e.g. I'm guessing that COPY_OS_4000_2440 and COPY_OS_4000_2443SD are selecting different COPY_GROUP_ directories to copy from and where to copy them, based on which mdoel, but what is 2440 and 2443SD, what is CAction (looks like it may be specifying files to delete) and the other Cxxx commands, what is significance of ~~U!V! (looks like an end-of-command token?), what are the various binary portions other than the string-lengths (which are obvious), what are the arguments to the various COPY_APP_ and COPY_SHELL_, COPY_PID_, COPY_NAV_ etc. commands, and so on... |

Is there any possible way for someone to upload this firmware update file? I'm going to try this on my 3200.... |

4040 Update- I found out that my USB cable was the problem. Bought a new one and USB works. Ran the clean install and everything came up fine UNTIL I hit 'Show Map'. Now I get 'Map initialization status: Please insert SD card with map." Well the Map files are already on the HDD as well as everything else.
I think this is related to two quirky things I found:
1) Under System Settings--Product Information-- Model Number is NA and serial number is blank.
2) On the HDD under SYS-USBTRANS- the UNIT_ID file reads Model Number=385840 and the serial number is blank.
It appears the serial number is no longer in flash. Anyone no how to resolve?
Help!!! |

Yarus, thanks for answering. Well I ran the update what appeared to be successfully. However, my 4040 would only make it to the warning screen then was hanging up and rebooting.
So, temporarily lost my mind and ran an 'update wince from SD (format)'. Now unit boots with a white screen and black progress bar. I plug in USB and I get a 'USB device not recognized' from PC. I have all files from original unit backed up; but, PC no longer recognizes 4040. I can get to the bootloader menu and do anything available on there. Anything that can be done? |

1. APP, USR and other directories will be created by the update program.
2. Yes the backup directory created by Magellan backup feature.
3. USBTRANS will be created automatically once you put empty SD card in and cold boot the device and do not worry about what Magellan says. It will work.

Question 1) After reformatting the TFAT drive you show only copying the MAP dir and the SYS dir back onto the newly formatted TFAT drive on the Maestro. What about the APP and USR directories?
Question 2)Can you explain further "7. Copy backup directory from SD backup (Step 5 Section 1) to SD card." ?? What backup directory? Are you talking about a backup directory that is created on the SD card when you run the Maestro's backup utility?
Question 3) Regarding running the update "8. Run Magellan’s 2.36 OS update (get it on Magellan’s website) and make sure to plug in external power while doing it."
In steps 6 & 7 you instruct us to copy the USBTRANS directory and the backup directory to the SD card. And then in step 8 run the Magellan update. Well, the first step of the Magellan update instructs you to put an empty SD card in the Maestro and turn the unit on and hook it up to a USB cable. Obviously, the SD card is not empty since we are adding USBTRANS and backup...will that be create a problem running the update?
