Hi fjf4,
Thanks for the question. I'm going to move this to the Home Theater forum so it will get the proper attention it needs.
Thanks,
Brandon
Hi fjf4,
Thanks for your inquiry. Your Lifestyle 28's Media Center is likely either a model AV18 or AV28 (depending on which series you own). If you could provide the serial number located on the bottom of the Media Center, we can determine this for you. The Lifestyle 48 systems use the AV48 Media Center. Since you may run into compatibility issues with your existing remote and speakers, we don't recommend using this Media Center with your current system.
We may also have service options available for your Lifestyle 28. I would recommend contacting your local Bose Technical Support Team by phone to determine any available options. Regional contact information can be found HERE. After selecting your region, navigate to the top-right corner of the page and select 'Support'. Then, scroll to the bottom of the page and select 'Contact Us'.
Best regards,
Brian
