Question about Car Audio & Video
You can try few things.
1. Add a longer and powerful antenna.
2. Open your transmitter. Please change the coil that is on the ferrite core.
3. Use new batteries.
4. Change the signal amplifier with a low noise high gain pre-apm.
This will solve your problem.

The outputs in the circuitry are getting weak causing the unit to fade in and out
It will need to be serviced most likely with a new board

HI.If you receiveD low frequency signal you may as well replace the crystal accesory to 10.7 mhrtz value.it has color brown. You may as well try to bring the equipment to a higher terrain.place wherein it recieves maximum frequency signal.This is a frequency signal capable in receiving frequency signal.Try to open the unit then replace that accessory that has color brown since this crystal will responsible on receiving maximum frequency.Hope this idea helps.

Try to check the resistors beside your 10 pin audio amp and driver transistors.

OK well what we do is warm the set up, and using a stuff called "Freeze Spray" we spray individual suspected components now the one that stops,or causes an obvious problem, is the one that's most likely faulty or involved, and stopping it from working, usually this is the culprit and replacement usually fixes it.
It also maybe a bad solder joint? So i t always pays to give all suspect or "Funny" looking solder joints a quick, "Lick of the iron" and reflow those joints again just to be sure...
Things that get hot, are usually the output semiconductors, ,aim audio amp, and power regulator and pass components so check here too.
As usual always start and check that the power supply voltages are all correct as if they aren't well nothing else can be? Check all Electro Caps, Vregs, Zeners, and output semis...

If your machine OK when its warm,,
the solution I suggest is to re-solder all parts using soldering iron and soldering lead..
after that try to test it by powering it on again..
thank you and don't forget to rate my answer..

Usually when units tend to operate when it gets warm, this is an indication of a thermal intermittent problem, usually common to poor or cold solder joints on an IC in the unit, I suggest you check all solder connections especially around any large Ic's mounted on the circuit boards and the power supply area.

IF you are having a fade problem and intermittent issues that appear to be related to heat, Get a can of freeze spray and have it till you find the component that shows reaction to the freeze.
