After this is done, your nuvi will show up in your computer like a normal USB flash drive. This will take some time, so just let it do its thing.Īfter the nuvi has been updated and has the latest maps, you must enable the Mass Storage feature so that you can browse the files using your computer's file explorer. The program will let you update your nuvi software and will install the latest map update. Step 1: Getting update files from the nuviīegin by plugging your nuvi into the computer and running GarminExpress. On a CTP11/CTP12, the 'Where To?' icon is a magnifying glass. You can identify the difference between CTP11/CTP12 and CTP2013 models by looking at the main 'Where To?' screen.

There may very well be other compatible nuvis, but I cannot comment on any other model. It will save a lot of the headaches caused from downloading maps from somewhere else. You can pick one of these up for less than the cost of a single official map update DVD, so don't be cheap and just pick one up. I recommend either a 3490LMT or a 3590LMT as those two models are guaranteed compatible with the CTP12 radio - aside from the JCV file. I highly suggest purchasing a compatible nuvi in order to have your own supply of map updates. The files in this guide were selected based on the files that were included in the now-unavailable 2014 offical map update DVD (which contained maps from 9 months ago) but tailored to the latest 2015.10 maps from Garmin. In light of this, I'm resigned to the fact that the only way that we will be able to get a full map update is to do it ourselves. It might be possible for an update DVD to be released, but I believe that it may have some features stripped from it in order to make it small enough to reliably update the official way. Note that there is no official update DVD for the '13-'14 models, and the official update for the '11-'12 models is no longer available. (Skip down to the my next post for update instructions) These radios do not have some of the same problems that the CTP2013 have since there are fewer files to install, but it's worth breaking it into two separate threads.

If you have a CTP13 radio, please see this thread instead: This is essentially going to be the same information as the revised CTP2013 thread, but tailored to the CTP11/CTP12 radios that came in the 2011-2012 model years.
