I was told that neither the look nor functionality of the navigation screen changes.
That would be basically correct. I upgraded to v4.73A from what ever my ’06 shipped with, and can’t say I noticed anything different... but then I’m only a casual Nav user.
The 2008 v4.64 had a few minor changes:
• One way streets (indicated with arrows
on the 1/20 mile scale - turn on in Icon
Options - "Other icons")
• Loss of male voice prompts (voice
prompts revert to female - regardless of
previous setup setting)
• Additional brand icons for restaurants,
motels and other POIs
• Updated maps and POIs
But the 2005 v4.13 had quite a few:
• Voice system enhanced to allow entry of
City, and Street. Allows entire address to
be entered by voice command.
• Route Guidance prompts includes street
name in guidance phrases.
• Avoid areas, and waypoint functions
added.
• For Odyssey, Ridgeline, RL, MDX The
2004 Zagat Survey ratings are available
for select restaurants.
• Navigation system utilizes Hands Free
Link (cell phone) to call POIs, and
personal address phone numbers.
• For RL Acura-Link Real-time-traffic c added
and displayed on navigation maps.
• For RL, MDX, Odyssey Navigation control
of XM audio.
• For RL Navigation system can control CDMP3
player, plays MP3 audio files.
• For MDX, Odyssey Navigation control of
Rear Entertainment system.
