My radio won't stay locked onto a station. When I push a pre programmed station like 107.3 it plays for a little while than randomly switches to 107.1 or 107.5.....and goes back and forth every few seconds. Very annoying. Any ideas! It does it with any station I put it on. The antenna seems fine.

most work like this turn the knob to the desired station , press the pre-select button and hold in until it is saved
then turn the knob to another station and hold in a different button until it is saved and so on until you have all of the stations on the pre-select buttons

Hello Linda Price...

Varies by make & model...
year would've also helped.

The most common way is to DIAL-IN the STATION
you want to PRE-SET you want ...

THEN simply push and hold
(just a good 4 second count ought be adequate)

Some radios give a beep to confirm...

There is (of course) another version ...
My wife's little German radio has a "memory" button...
"Position" over the station you want...

Press the MEMORY BUTTON... THEN the station
PRESET... & release.

BINGO...

The actual way to find out is to read the owners manual.

For USA models MANY FREE manuals can be down loaded

ENTERING SECURITY CODE

Most vehicles are equipped with Heidelberg V or VI radios that are equipped with a theft protection program. When the battery has been is disconnected or if the radio has been removed, the radio will lock-up electronically and cannot be operated until the security code is entered. On the Heidelberg V, if the proper code is not entered in six attempts, the radio will lock-up permanently and cannot be repaired. On the Heidelberg VI, two incorrect attempts will lock the radio for about 1 hour.
The Heidelberg V may have a code assigned at the factory or a personal code created by the owner. The Hiedelberg VI has a code assigned at the factory and entered by the dealer during pre-delivery inspection. New radios come with the code printed on a sticker but not entered into memory. All codes are 4 digits. To code the radio:
Heidelberg V

1. Turn the radio ON . The radio should display the word SAF. DO NOT attempt to eject a cassette with the radio in this mode.
2. Push the AM/FM and SCAN buttons at the same time and hold them until the display changes, then release them immediately. The number 1000 will appear for about 3 seconds, then the display will go blank. Release the buttons then.

NOTE If the buttons are held too long, the radio will interpret this as an attempt to enter an incorrect code.

1. Use the first four station selector buttons to enter the code. The first digit of the code is always 1. Each time the other buttons are pushed, the number in that position will change.
2. When the code appears correctly in the display, push the AM/FM and SCAN buttons at the same time. When the radio plays and displays a frequency, release the buttons.
3. If the code was entered incorrectly three times, momentarily disconnect the battery and try again. If the code is entered incorrectly three more times, the radio cannot be coded and cannot be repaired.

Heidelberg VI

1. Turn the radio ON . The radio should display the word SAF. DO NOT attempt to eject a cassette with the radio in this mode.
2. Push the AM/FM and SCAN buttons at the same time and hold them until the display changes, then release them immediately. The number 1000 will appear and remain in the display.

NOTE If the buttons are held too long, the radio will interpret this as an attempt to enter an incorrect code.

1. Use the first four station selector buttons to enter the code. Each time a button is pushed, the number in that position will change.
2. When the code appears correctly in the display, push the AM/FM and SCAN buttons at the same time. When SAF appears in the display, release the buttons. The radio should play and display a frequency.
3. If the code was entered incorrectly two times, leave the radio ON for one hour and try again. This can be repeated as often as required.

Car wont start when i turn they key. The battery is fine. Its a connectivity problem between the ignition and the starter. How do I go about fixing this?

FixYa,
I went back to "Best Buy" installers and they quickley pointed out that I had pressed the scan button, and that it was still activated.
I pushed the scan button again, that turned it off, and the new sirrius satellite radio is now working perfectally.
"Thanks"
