How do I preset the stations for an Alpine TDA-7547 car Stereo. This is an older stereo and setting the stations is not intuitive.

You can get one from pacparts.com or any decent car audio store. The part number is AL16-0001.

Make sure the yellow wire is connected to a source that still has voltage when the key is turned off. The yellow wire controls the memory of the deck.

Theres a standard amongst most stereos, so if these colors apply, then you will be right,
Red is Ignition power
orange is direct power
Black is earth
blue is for phone
White is for electric arial
then there will be four coloured wires with matching color trace wires, these are the speaker wires.
Hope this gets you going, good luck.

Manuallly set to the station you want,then pick a preset button & hold down until you hear a beep or 4 about 5 secs

To change AM to FM, hit the White Band Prog button. Still don't know how to change time though.

Here's the manual:

tune to station ,press (for example)1 and hold till it starts blinking , then press 1 again,continue in this manner until you've set all presets.

On the face of the stereo is a * button. Push this button then use the numbers on the face of the stereo to go directly to that station. Example, my favorite classical station is 90.7. Push the * then 907. This station will appear in display. Then push and hold for about 5 seconds the preset button you would like this station to be. The stereo will momentarily blink to a different station then come back. Station set.

You need a pair of alpine radio removal keys which get inserted in the slots along the sides under the trim ring. Any Car stereo shop should have them for free(ish).

It's probably a solder in lamp. They can tend to be very tiny. About the size of the head of a paper match or smaller. If you're not good with soldering then I would suggest you go to a repair shop and let them do it. Good luck.
