Motorola Droid X :: Speaker - Design Flaw - Fixable

Lot's of talk about the speaker volume/tone on the Droid X.

I too am a bit concerned with the speaker volume and tone on my Droid X.

I did a test. Droid X vs. Garmin Nuvi GPS - Google Nav vs. Garmin built in maps.

I plotted a route across town and fired up both units in my car. I turned on my car radio. I started to drive.

Results:
1. The Garmin was louder and clearer than the Droid X when speaking turn by turn instructions.

2. The Garmin was loud enough while listening to the radio.

3. The Droid X was not loud enough to be heard over the radio(volume set to max).

I don't want to plug my Droid X into the AUX on the radio because I then lose use of the radio.

Is this a hardware issue in the Droid X or something that can be fixed by a software update?
