The internal software in most digital avalanche transceivers can be updated. This feature (pioneered by Pieps) allows you to update your beacon with new features without purchasing a new avalanche transceiver.
The Pieps DSP Sport and Pieps DSP Pro were designed to be user-updatable, but this feature (specifically, the cable that is used to update these devices via the headphone jack) was never released to the public. The Pieps Micro can be updating using a Bluetooth enabled Android or iOS device. The BCA Tracker3 is user-updatable using a USB cable.
Other transceivers (e.g., those manufactured by Mammut and Ortovox) can be updated at selected retails stores whereas other manufactures require that you send your transceiver to a service center.
Updates to ARVA transceivers are free. Other manufactures charge an upgrade fee of $20us to $30us.
