Sony CDX-F7750S Hi I have recently installed a Sony CDX-F7750S I have tuned the radio and preset the stations, the way the manual showed, they work for my journey, and then when i turn my car off, they are no longer stored! How do i sort this problem? Please let me know! Thanks, Chris

1. Connect the FM antenna and the AM loopantenna at the back of the unit. Rotate the AM loop for better reception.
2. Press AM/FM.
3. Tune a station by pressing TUNER+/-repeatedly until the desired station is found.Alternatively, you can press and hold thesame buttons down for about one second toactivate the automatic search function. Inthis mode the unit will automatically tunefrequencies until it finds a station.
4. Repeat step 3 to tune to another radio station.
5. Press AM/FMto select between FM and AM.Storing Radio Stations

The unit can store up to 40 radio stations (30 preset stations for FM and 10 preset stations for AM) in its memory. You can enter every single radio station yourself or the unit can store all available radio stations automatically in ascending order

Automatic Preset Programming
1. Press AM/FM to enter the AM/FM mode.
2. Press and hold AM/FM for two seconds to start automatic preset programming.
3. Radio frequencies will be browsed and radiostations stored automatically. When all the available radio stations are stored or all 40(30 preset stations for FM and 10 preset stations for AM) memory locations are full,the auto preset programming function will stop.

Manual Preset

2. Press MEMORY. While the Program Preset number is still flashing, input your desired preset number using the numeric buttons or press CH+/-, then press MEMORY to store it.

Retrieving Preset Stations
1. Press AM/FM to enter the Tuner mode.
2. Press CH +/- to search up or down for thepreset stations or directly press the numeric buttons.

hi shawn, try deselecting the TA feature of your unit and then try tuning for stations. before doing this i assume your antenna is in good working condition. if this does not solve your problem, then "reset" the unit and retry tuning for radio stations. reset switch will be found on main unit behind the face. cheers.

Hi, Just tune the radio station in with the seek buttons then hold down one of the 1,2,3,4,5,6, buttons in for 3 seconds and the headunit will beep and lock in the preset

Cheers Brad

Sony XPLOD CDX-GT200 CD Player
Radio:
To receive store stations(press); store stations (press & hold). Preset tuning is not possible, however one can store the correct frequency in the memory.

Manual storing:
while receiving the station that you want to store, press and hold a number button(1 to 6) until "MEM" appears. The button number appears in the display. PS: If u try to store another station on the same number, the earlier station will be replaced by the new one............................................sodeep

Press Function button at front of unit until display shows Tuner, and press Preset + / Preset -
If you want to listen Non-Preset stations, press << / >> keys of remote to tune a station. That's the procedure.
If built-in remote in your mobile have above said << / >> keys, you can tune station frequency.

You will need to use the Forward and Reverse buttons on the CD player. Set the station by holding the button you want to set it to until it blinks and shows the station number.
To set more that 10 stations. Press the (>10) button and then enter 11 or 12 or so on and set the stations the same as above.

you need to remove the radio and swap the red wire for the yellow wire and vice versa, they have bullet connectors to allow you to do this, basically the permanent live and the ignition live are the wrong way round.

check the wiring and see if you constant power is connected if its not connected you don t have no memory on the unit if its connected check constant power fuse on car
