When Nokia announced their music player capable phones they neglected to mention the lack of support for external headphones. This mod includes an analog volume dial integrated into the push to talk unit. The HDS-3 cable ships with the 6230 and other Nokia phones capable of stereo playback.
Before starting, a quick rundown of some other Nokia models of pop port
headphones and adapters include:
Nokia
HS-3 “Nokia Stereo Fashion Headset” white or black, smaller push to talk
unit than the HDS-3, headphones are still of an inferior audio quality
Nokia HS-8
“Nokia Activity Headset” ugly and bad audio quality headphones
Nokia HS-6
“Display Headset” lcd display and controls for audio and calls, but yet
again no port to plug in your own headphones
Nokia
HS-23 “Nokia Stereo Headset” includes volume control, lesser quality
headphones
Nokia
AD-15 “Nokia Audio Adapter” allows you to plug in your own headphones,
unfortunately this is achieved with a big box on the end of the cable, there is
no mic, and as far as we can tell no button to switch tracks.
Even headset models that are not available on the market yet don’t allow
for the consumer to plug in their own headphones. Why Nokia? Why! For a few
weeks we assumed that the audio quality coming out of our 6230 was just as
dismal as the headphones in the HDS-3 headset led us to believe. The astonishing
part is that no, the audio quality of the 6230 is comparable to most mp3 players
on the market once you manufacture your own adapter cable.
The second mistake by Nokia is the misinformation as to how much memory can
be recognized on the mmc cards. The manual
for the 6230 states the mmc card can be up to 128 mb. In reality the phone can
recognize mmc cards up to 1 gig. To see if your phone’s firmware is up to date
enough to work with that much memory, in the 6230 type: *#0000#. On the screen
you should see something similar to:
Nokia 6230
V 05.24
25-11-04
etc.
The important information in this is of course the firmware version on the
second line, in this case 5.24. If your phone is not up to date you can have the
firmware flashed at most cell phone provider stores. Note that firmware upgrades
will wipe the memory of the phone, so be sure to save important info before
upgrading. The firmware of the 6230 starting with version 4.44 should correctly
recognize 1 gig of memory on the mmc, but may not search the subdirectories on
the card for music files to include in the playlist. Before loading audio on the
mmc card, we suggest you format it in a card reader on your computer rather than
on the phone. Format the card, re-name the card, then fill that 1 gig of
happiness with a playlist of mp3/aac and/or mp4 if you have a Nokia model that
supports it.
