I know your guys answer will be a full audio upgrade, but this is a business vehicle, so I don't want to put any great amount of money into it.

Is there any way to be able to integrate my mp3 player into this vehicle? I have tried FM transmitters, and the ones I have tried suck. Is there any way to wire in a 3.5mm jack into this vehicle so I can just plug in?

Specs are:

2007 Mazda5
factory single CD system
Does have a sat radio option, but I don't have it enabled

Any help would be appreciated!

The iPAC-OEM provides direct sound from your iPod into a factory stereo. Get clean, high quality sound playing through your factory radio. The iPAC-OEM consists of a universal auxiliary audio input interface and an Apple iPod connector cable. To use the iPAC-OEM with your vehicle, you will also need a vehicle specific adapter harness.
• Works with iPod mini, iPod video and 3rd generation iPods.
• Charges the iPod.
• Change tracks on your iPod from the factory radio or steering wheel controls (vehicles with audio controls on steering wheel).
Note: The iPAC-OEM will only work if the vehicle does not have a separate CD changer, XM tuner or cassette player. If a radio controlled accessory is present it will have to be disconnected.
