Thank you for your post and welcome to the Community!
In regards to your query, are you referring to making your SoundTouch 30 Series 2 Bluetooth compatible? If so you may be able to achieve this with a 3.5 mm Bluetooth adapter which you could plug into the AUX source. Please bear in mind that we cannot guarentee the functionality of our systems with 3rd party products.
If there is anything else I can do, please reach out to us again!
