About 2 weeks ago, I installed multimedia interface, a pioneer dvd player, front and reverse camera. And after using these for couple of weeks, I realize something is not right. The radio reception from the dvd player is just crap. It is worst than the fm booster (I was told it has to be removed coz it conflicts to the dvd player. I doubt it now). FM can't tune to some local stations and most tuned stations are worst than proton car's radio. Tuned stations in higher frq like 95.8, 97.2 in JB deliver unconstant tone. Believe or not, I can't find a single station at all in Batu Pahat! Not to mention in the PLUS. I notice I paid for an radio antena which is sticked on top of the inner wind screen. I went back to the shop. The boss said I need to install an additional 'signal booster' but it was out of stock and ask me to wait. The sound qulity of MP3 played thru USB of the player is also unacceptable. Ok, I don't know whether the installation method is right thus need your advice. The dvd player is actually taps to orginal radio station at 88.7. When I player anything from the player, I need to switch to FM at 88.7. Besides, the reverse camera was initially working fine. The Idrive sometimes prompts the license plate bulb need to change. So, i went back for help. The same guy added a ic in between the camera cable. Guess what? Now the reverse camera is burned!!! Can anyone comments whether the installation is correctly done? Can I utilize the original shark fin attena without adding any extra attena? How can I get better MP3 quality?
