Hi Nick
Welcome to the Forum. (Note when replying to forum emails please do so using the Forum so that we can all see the thread, - many new users do not know this).
you say:-
However, I sometimes have difficulty switching between different cd’s and from a cd to radio and vice versa.
Can you please tell us more about how your B2 is set up and which version of the Operating software it is using.
Using the Remote if you press the "info" button twice the Software version will appear on the front display.
We would also like to understand the strength of the WiFi signal that your B2 is seeing using this command under the "maintenance" menu from the front controls
the value you get (assuming you are connected by WiFi and not Ethernet) should be LESS THAN (-50), a larger number is bad a smaller number is good.
Also please run an "Scan Disk", again from the Front controls
Finally (for now) sometimes problems are actually caused by the device you are using to connect to your B2 - Phones and Tablets (especially Apple products) tend to "cache" stuff for you, so can you tell us a bit more about
what you are using in this area.
Fred
