Thanks for posting this app.

After much trial and error I was able to get this to work on my NUVI 350.

I was unable to install the app using a 2GB PQI SD card (7 digit ID).
However, I was able to install using 512MB Patriot SD card (10 digit ID).

Apparently the SD card brand plays a big role in determining whether the app will install or not. It may be you need to use an SD card with a 10 digit ID before the NUVI will install from it.

I used the “garmin_keygen_v1.5.exe” keygen, SD card ID, and selected the “Garmin Language Guide” in the “Select Map Product:” field. I then added the generated number to the “gmapsupp.unl” on the SD card and then inserted the card into the already on NUVI. The NUVI then prompted to install new data.

This is the actual keygen I used: [Only registered and activated users can see links. ]
