- Apple iPod/iPhone software updates may change functionality
results. If you download a newer software version, you may need to
reset the head unit and your iPod/iPhone to regain functionality. If
this doesn't work, you may need to wait until a newer software
update is available.
iPod Text: Artist name and song title can be displayed on your
factory radio using the GM radio's XM band.
None: Some GM radios will only allow disc
number and track number to be displayed.
Operation Modes: The iPod interface adapter features the
following modes of operation:
- Direct Mode: In the Direct Mode, the LCD screen and the controls
of your iPod or iPhone remain functional. In this mode, you can control your
iPod or iPhone's music using the iPod or iPhone's click-wheel or
touch-screen. You also have track up/down controls from the GM radio. No
text will be displayed on the factory radio in this mode. In addition,
Direct Mode allows the playing of streaming music applications, such as
Pandora.com, and SIRIUS XM Online radio from your iPhone or iPod touch.
- Folder Mode: Folder Mode allows you to access 4 folders -
Playlist, Artist, Songs, and Album on your iPod or iPhone from the GM radio.
Your iPod or iPhone's folders are accessed with the factory radio's preset
buttons. You will be able to view artist and song title information on the
LCD display of your factory radio. Your iPod and iPhone's screen and
controls will be locked.
- Playlist Mode: This mode allows you to access Playlists and Songs
on your iPod or iPhone from the GM radio. When the iPod or iPhone is
connected to the GM factory radio via the PA15-GM, the interface scans all
available Playlists and folders on your iPod/iPhone and will automatically
assign the first 4 Playlists in alphabetical order (they must be Playlists
you created in iTunes). Your iPod and iPhone's screen and controls will be
locked during connection. The factory headunit will not display artist name
or song title information.
Note: To switch between Operation Modes, you will need to
configure the dip switches (1-4) on the side of the interface.
App Streaming (in Direct Mode): Direct mode also lets you
listen to the sound from your iPhone's downloaded music apps (such as Pandora,
iHeart Radio, SiriusXM, etc.) through your factory head unit & speakers. You
will continue to control your iPhone's apps & view song/artist information from its touchscreen.
Note: Your iPhone will need an active Data Plan account
with connection to the Internet via 3G, EDGE, or WiFi. You will also need
applicable music service accounts.
Auxiliary Input: In addition to the
iPod input on the PA15-GM, there is an auxiliary input (stereo RCA) for use with
another source, such as a DVD system, satellite radio, or game system. This aux
input can be used with or without the iPod connected. To use the auxiliary input
on the interface, dip switch #1 must be set to the "On" position.
