I want to be able to offer a genuine copy of memory map to work with a cheap CE car navigation device.
You can get it working by following these instructions. However, I want a program writing that will do all of the work enclosed in the instructions below so that a user can simply run both programs to get the software to work on their device.
Must work on windows desktops, either XP or Vista / Windows 7.

thought I would share some of my experiences with trying (and succeeding) to get Memory Map
charts to work properly on a cheap big-screen satnav. The Road Angel Adventurer offered by
Memory Map is fine, but very pricey (IMO) at £250 for a decidedly average 3.5" Satnav with
£40-worth of maps.
Penny shown for size (well, I thought it was a penny, but it's 5c which is the same size but
If you want to do this you end up with a 4.3" MyGuide 4228 satnav (cost £65 from ebuyer, link)
with as much of the UK charted as you want, at £20 per chart. The charts are properly
calibrated CAA charts, exactly as you buy on paper. All in all, I have England, Scotland,
Wales, Northern Ireland and Northern France covered at 1:500000 for £40. They can be bought
here. Finally, it is advisable to buy a cheap 2GB SD card, but you can use the one that comes
with the satnav if you never want to use it as a road satnav in the future (advise against
On your PC, you will need to install the software from the Memory Map disks, and also either
Vista or the latest ActiveSync from the Microsoft download site if using XP. Finally, you need
a program called ceregeditor to change one of the registry values on your satnav (free
1. You need to download this file: [url removed, login to view]
Extract the contents and using a card reader, put them into a file called MobileNavigator on
your (previously blank) SD card.
2. open the folder you have created above, and rename the file called [url removed, login to view] as
[url removed, login to view]
3. Using the Memory Map OS application on your PC (from the Memory Map CD's you ordered
earlier...), Select Map>Map List then select your CAA charts, and select Send to PDA. You can
then select the drive that your SD card is in, and upload them. You can do this using
ActiveSync, but it takes forever.
4. Connect your satnav to your PC using the supplied USB lead, and allow ActiveSync to connect
to it. In ActiveSync, Select Tools>Backup/Restore , and then make a backup (in case you mess
something up and want to get back to the start). Remove the supplied SD card from the satnav
(this holds all the road-based software) and insert your newly programmed SD card into the
satnav; turn it on and allow it to boot up. The press "Navigation". Memory Map will load up,
but you are not done yet. At this point, all your maps are viewable, but the GPS functions
will not work.
5. You now need to connect your satnav to the PC with the USB cable. ActiveSync will detect it
again. Using Memory Map OS on your PC, register your maps using the Help>Register License
command. Once you have done this, a message will appear on your PC screen saying that
registration details have been sent to the "PDA" or satnav in this case.
6. Download this file: [url removed, login to view]
Extract it to somewhere convenient on your PC, and rename the .exe file as [url removed, login to view]
In ActiveSync, select "Explore", look in the folder called SDMMC and locate the file you
previously installed as [url removed, login to view] in step 2. Drag your new [url removed, login to view] into
this folder. When prompted whether you are sure, say yes. It will overwrite your previous
file, and this is what we want.
7. open CEregEditor, and select Connection>Connect. Using the left hand frame, navigate to
Now change the value to read: 1,0,COM1: ,4,1,0,0,-,1,6,100,500
Exit CEregEditor. unplug your satnav from the USB cable. Press the reset button on the back of
the satnav with a paperclip.
You're done. That's it! Easy eh?
Little of this is my own work; it has come from many forums and sources, none of which offered
solutions that worked in their entirety (on this satnav, anyway, not tried it on any others).
This walkthrough works on the MyGuide 4228, and may well work on others, but I don't know
about that. No guarantees are offered, and you do this at your own risk. I recommend you use
ActiveSync to make a backup before you start, and by restoring this backup and using the
supplied SD card, you are back where you started.
