Don't know what is with GE but with map updater you can update map after erase reg 41
I haven't been able to replicate that with MU using a nuvi with 41 erased. I get the same message with both GE and MU as gpscurious stated:
"The update is unable to determine where the specified map file should be written. Please contact Garmin customer support: http://www.garmin.com/contactsupport".

Loly are you doing something to enable MU to install/reinstall LM maps? The map img download is not the problem, both programs for me simply baulk on transferring them onto the device.

I go to my garmin and there is nuvi recognized and i can download map and that map is unlocked when is downloaded.
I do agree with Loly on that first part though Caty. The Unit ID is still in GarminDevice.xml created after 41 is erased. The unit registration and unlock codes are missing and model number disappears in that it goes to basic [becomes 24xx; 37xx etc] and with some units certain functions present in senior models do not work although this didn't happen with his 2460.

Regarding MyGarmin, loly are you saying that if you attempt the map update/reinstall with MU and it baulks you can then go to MyGarmin and complete the dl there. Again, if so, i can't replicate that either.

When anybody buy new nuvi two things that must do is:

1.) Complet backup of internal storage of device
2.) Backup of region 41.
Wise words. Maybe also 3.) should also do complete sd dump of all other regions. But as far as the nv re-populate is concerned some ppl obviously know how to repair it before writing 41 back so that the codes can be recognised again and written into the xml. [Not me, i'd have to ask for your help Loly kunix et al.]
