Need some advice who to take my car to in Fourways or Sandton area please besides the agents who will charge me a small fortune.

I blew a fuse recently in my car and replaced it, since then when driving the radio reception is patchy, you hear perfectly then hear white noise then it comes back soon after.
I am not sure if perhaps the fuse replaced could be too high? Would that make a difference?
I dont know where to start to troubleshoot it.
Any advice would be appreciated.

Thanks

Replaced with the same colour code? Even if it was a high rating it would not result in this noise, it would just mean the protection is not good, in case of a fault it would allow too much current instead of blowing.

What caused it to blow in the first place?
 
Of all the things I know about car audio, I know nothing about radio and reception problems.
 
Have you been messing around with the wiring? Added an amp perhaps?
Make sure your ground wire is intact.
If you have added an amp with RCA, get yourself an RCA ground loop isolator.
They are quite cheap and should help

Does the fuse fit snugly? Also, to rule out the fuse as culprit, remove the fuse and bridge the fuse-slot with a piece of electrical wire. If the issue persists, your problem is elsewhere. If it is the fuse, just don't bridge it permanently. Those things are there for a reason.

It can't be the fuse, the only difference between the fuse and the jumper would be the max current rating, that's all. Perhaps the most logical idea could be that the circuit/component related to the fuse suffered some damage as a result of the short.

Yeah, I actually think you are right.

Long shot.....Maybe your RDS AF (alternative frequency) setting its switched off, or defaulted to off when fuse blew. This will have the effect of not maintaining the optimal frequency for that radio station, as you driving around.
 
Also - most car radios have a setting that alters the gain for local or distant radio stations - usually marked LOC/DX (or sometimes as Local/Regional) - In LOC mode, searching forwards or backwards through the frequency range will skip past the weaker signals and only stop when it reaches a strong one. You should be guaranteed of decent quality audio. Switch to DX mode, and it'll stop on the weaker channels too.

Did not solve issue, I wonder if the aerial on window is damaged?
