MICHI X3 Bluetooth 5.1 AptX HD Module Owner’s Manual
Michi Bluetooth 5.1 aptX™ HD Module
The latest Apple iOS version (including OS V15.7.2) may cause the APPLE MUSIC
app to stop playing audio when manually jumping between tracks in a playlist.
The Bluetooth connection is maintained but there is no audio output and no
playback information (sample frequency and/or bit rate) displayed. A hard
power cycle of the unit remedies this issue.
Earlier versions of iOS do not appear to have the same issue. Other iOS Apps (i.e. iTunes, Spotify, Tidal, etc.) are NOT affected by this use case.
If this is reported, please contact Rotel at sales@rotelglobal.com to order a new Bluetooth 5.1 module (Rotel Part Number: 093E-BTM0002-D-3) with updated firmware V1.04 (or newer) that resolves this iOS compatibility issue.
Note: All new delivered spare parts will be programmed by new firmware V1.04 (or newer) before package and shipment from now on, either of below two methods can help to identify this change.
1. Check and ensure a printed label with text “V1.04” being pasted on plastic package.
2. Or check and ensure the last 5 digits on the pasted BT ADDRESS label are higher than “28780”
Bluetooth module replacement requires removal of the top cover and replacing the Bluetooth module in the socket (no special tools or soldering is required) as shown below.
Affected unit models include: X3, X5, P5, X3 Series 2, X5, Series 2, P5 Series 2
