BSW E53 Radio Upgrade - confused?!?!?

[Rogertw]

BSW's site offers an upgrade to the professional radio which offers mp3 compatibility:

"By replacing your BMW radio with a newer, Plug and Play (under 15 minutes!) version from BSW, you can add the latest technologies to your BMW:

• Upgrade from that archaic cassette deck to an in-dash CD player!
• Ability to add Fully Integrated Satellite Radio (Sirius Direct or XM Direct)
• Ability to add iPod integration
• Ability to add an Original BMW Auxiliary input (sold at your local BMW dealership)
• Read MP3 / WMA burned CD's

And because this is a factory BMW Business CD unit, fit, finish, and quality are perfect. In fact, if someone put this in your car and didn't tell you, you'd never know!"




however, they state:

"This upgrade applies only to vehicles produced on or before 08/02; later vehicles already have this upgraded radio so this upgrade is not required."

I have an 04 E53, with nav. My radio is certainly not mp3 compatible, there is no 'aux in' that I can find nor any other way I can fit external sources.

I want to add mp3 and also backup cam, I would LOVE some help from someone who has done this.

Searching the forum just increases confusion ?!?!?

Sorry, total NOOB!
