SOFTWARE VERSION: PR 1.2 10.2010.19-1 (Settings > General > About product) EXACT STEPS LEADING TO PROBLEM: 1. Open Media Player and play any song you like. 2. Turn On FM-Transmitter 3. Tune your RDS-capable radio (i.e. your car radio) to the N900's frequency EXPECTED OUTCOME: The RDS-capable car radio shows at least the song title as the N900's station name. PR 1.1.1 used to be able to show Song Title, Album and Artist. According to Andre Klapper in this post below, PR 1.2 is supposed to transmit the title of the song. https://bugs.maemo.org/show_bug.cgi?id=7353 Notice that other people experienced this bug too. (http://talk.maemo.org/showthread.php?t=52797) ACTUAL OUTCOME: The RDS-capable car radio just shows "Nokia", just like before the PR 1.1 update. No song information is transmitted. REPRODUCIBILITY: always EXTRA SOFTWARE INSTALLED: fm-boost Simple FMTX desktop widget OTHER COMMENTS: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; de; rv:220.127.116.11) Gecko/20100401 Firefox/3.6.3
N900 support RDS-PS and RDS-text. If radio doesn't support RDS-text then Nokia is show on display. There is problems with some station names which are over 8 char long which is maximum size what RDS-PS can display. For that reason station RDS-text is which shows the station name.
Confirming. (In reply to comment #1) > (...) While this may be true, the bottom line is that this feature worked before PR1.2 and now it doesn't.
I can confirm this bug being present in PR1.2 final too, while it worked fine in PR1.1.1.

It still works. It's not really the Maemo software's fault that your particular radio only supports RDS Title display and not RDS Text display. Most new car radios support this by either automatically displaying the RDS Title and then the RDS Text, or by having a RDS Text button that can be manually toggled.
"In PR1.1, Media player used PS field to show the RDS data. Then we got a bug report because we were violating RDS specification, RadioText field should have been used instead. There was long discussion which one should be used, because there are not many car radios in world that supports RadioText. Final decision was to follow specification even in many car radios the rds data is not going to be shown anymore."
