Hi,
I have installed Maps 3.0 on my E71 [version: 210.21.006, RM-346, E71-1 (26) ].
Start the 3.0 Maps application, and: nothing.
It simply did not run.
More over, while down-grading to Maps 2.0 the E71 simply complete crashed, deleting all on-device-memory information (I had to restore all information from the backup).
More details:
1) I used the applications: NokiaMaploaderSetup.exe, Setup_Nokia_Maps_Updater_1.0.6
2) I have the latest/greatest Nokia-PC-Suite
3) With the previous version of the Maps 3.0:
The maps still did not worked, but I was able to downgrade to 2.0 easily.
Thanks for the support, Shay
