I’m with BMW of North America, LLC. We’re glad to hear that you’re enjoying your new 530i with sport package.
Regarding your iDrive question, you do not need a handset installed in your new 530i to use the BMW Assist through the iDrive. Any 2004 BMW with BMW Assist does not need a handset installed in the vehicle. Also, for MY2004 (> 09/03 for 3 Series) the BMW Assist option includes its own GPS receiver and antenna, eliminating the need for the On Board Navigation System on all models except 7 Series, where it is standard.
BMW Assist is an invaluable group of services that help ensure your travel safety, security and convenience. With BMW Assist, you have 24-hour-a-day access to Emergency or Roadside Assistance at just the push of a button or even automatically in the event of a serious accident. Our Convenience Services will help you get things done, in and out of your BMW. Your BMW Assist Concierge personal assistant can help buying concert tickets, making dinner reservations, finding the perfect gift, or planning a vacation. Just call this service by dialing 800-233-8896 toll-free from any phone, any time. This makes the service valuable at home, office and vacation, not just when you're in the car.
If your iDrive screen is not working properly and you or your center need our assistance, feel free to call BMW Customer Relations at 800-831-1117 and mention Reference #200423700572 so that we can help you more efficiently.
