Techniques facilitating locating an implantable medical device (IMD) within a body of a patient are provided. An estimate of the location is determined based on strength information representative of strengths of communicative couplings between a communications head device and the IMD at various positions of the communications head device. The strength information can be updated periodically or based on specific events, such as changes to the body and/or an amount of time elapsed since strength information was previously obtained. Media representative of the estimate of the location and an image of the body can be output and can facilitate a patient or caregiver locating the IMD. In some embodiments, the media and image output can guide future placement of the communications head device on the patient to efficiently establish communication. Further, in some embodiments, numerous IMDs implanted within a single body can be identified and communication can commence.
