Deh7300bt shows ready instead of Bluetooth menu

I am assuming you are trying to pair iSound BT200.
See Page 6&8 of the ISOUND BT 200 User Manual

During the first time set-up, you must hold the
power/phone button down until you hear a voice say
"Power on" then followed by "Ready for pairing" in order
to sync your device to Bluetooth. After the initial pairing,
you can let go of the power/phone button after you hear
"Power on".

When a user is connected and the BT-200 is o , press ff
and hold for at least 5 seconds to unpair on Bluetooth
(allow another user to connect)

press and hold the BT (bluetooth) button on the left side of the radio for about 5 seconds. wait for the bluetooth symbol to show up on the screen and start blinking. While its blinking tell your phone to begin searching for devices. your phone will find the xplod deck and ask for an access code (the code is 0000). Once found the bluetooth symbol will stop blinking and stay solid and a picture of a phone will show up on the stereo screen.

Ok, I have a Sony MEX BT 2600. To pair my phone to the radio, I had to press and hold the BT button for 5 seconds until it flashes, then I have to search for devices on my phone. Xplod comes up. When it does, pair the two and use code 0000. That should do it. Also make sure the BT icon is showing, meaning it is activated for the Sony to connect. When conncted, the radio should show a phone icon for the BT Phone segment of the radio, and then another icon for the BT Audio, both should what looks like radio waves coming off of them, meaning the two devices are connected and recognizing each other.

There is a file that needs to be downloaded to the Pioneer using the Software Update facility. You can get this file from your Pioneer dealer. After this, you will need to play with your device until you get the BT Audio to connect properly, then connect the Telephone. I spent about an hour trying this and then I was successful. My Nokia E71 now connects when I start the car on both the BT Audio and Telelphone connections without continually disconnecting.

hey
the pass code for BT-020C is 1234

i'm not good in english but i'll try. i used h-700 which i think they are same, you have to close your boom(BT) first and and hold the call button for few secs then open the boom while the light is show(still push the button) then release the button then you open your phone and open bluetooth menu choose search for device, your bluetooth should appear on the list.
