Thread: Garmin cityXplorer Sydney - Sensis & Navteq v.20.12 & updated Navteq 2012.20

I have encountered an interesting problem I have not seen here before. When I followed the instructions to unlock CityXplorer Sydney with Jetmouse KG and transferred the img and unl files to my SD card /Map folder it worked beautifully (showed up as Powered by Cityxplorer - was able to simulate a route etc.). I then proceeded to Melbourne, used the same procedure - Jetmouse with same ID (2354 for CN AusNZ 2012) and PID2 settings. After transferring it to my Nuvi (same directory SD/Map as Sydney) and powering it up, the message appeared 'cannot unlock maps' and Melbourne was not seen in the Map info screen as was Sydney. I then tried Brisbane and Adelaide following the same procedure with the same negative result. Has anyone come across this before. Can maps unlocked using Jetmouse with the same ID signature (although with different unl file names) not be used in the same GPS?

No luck even after I bought a micros SD card.
2354, 2,1,1 and unl + img in X:\Garmin\Map
Any hints??? Cannot see it listed. Nuvi 2360LT
Maybe I should try the other maps for 37xx series?

Kenta2, Thanks for your reply, but that is not the issue. I am doing it exactly as you mentioned.
Thanks Cat - FID 800 with 37xx maps worked. I can see that the problem is gma.

Actually, some progress now.
Moved unl + img to X:\Map and now I get cannot authenticate maps.
What am I doing wrong? Thanks!
