I cant unlock maps in my garmin nuvi360 - Garmin eTrex Summit GPS Receiver

Contact Garmin for help ( email).....they will get back to you ASAP if you say your going away

Details on unlocking maps for Garmin Nuvi satnavs are at http://www.fixya.com/support/r6197735-no_detailed_maps_found_support_routing
StreetPilot satnavs probably use the same method. You may need to skip to paragraph 2 and start from there.

The Garmin Maps require a map unlock code in order for the GPS to be able to open/access it. Since the maps are copyright protected by Garmin you should of recieved the unlock code from Garmin when you purchased the new map update.

i have no signal on my gps nuvi360

Map unlock codes are specific to each unit. You will need to contact Garmin to obtain a code to unlock the maps.

Where did you download the Australian maps from? If from Garmin, contact Garmin for the unlock code. Maps have to be unlocked to a specific unit.

If you downloaded the maps from the internet, you will still need to contact Garmin for an unlock code.

What is the Garmin 510 that can't unlock maps stating exactly? And to Nici07 who said, "Need to unlock device", are you referring to a PIN lock or locked maps?
