The code supplied for my Nissan Note Connect combined radio / CD / Sat Nav worked first time - no issues and no having to go back and ask for a second code because the first one didn't work. Warning to other Nissan Connect users - to get the information for the code I had to put in 3 incorrect entries first. This leads of a 60 minute timeout before retries. However, the timeout is not elapsed time, but ignition on time. If, like me, you do not park you car in a garage, this means you have to drive around for 60 minutes before you can use the supplied code. As I had no need to do anything other than short trips for a few days, this meant 4 days between code supplied and code used
