Question about Panasonic CQ-DVR909U Car DVD Player
I got for Christmas a new car stereo: DP AudioVideo model DP432. With the old stock radio, the AM reception was just fine. Now with the new system, only the FM comes in good. The antenna is grounded just fine. Any suggestions?
I thought about not using the antenna in the back window and instead, slide another telescoping antenna in the space under the dash.
The car is a 2002 Altima.
AM.... what the heck is AM??? LOL
Check the antenna connection behind the radio to be sure it is taped and not touching ground. Also the antenna & cable running to it for worn spots in the shielding, or corrosion.
I think (based on knowing how manufacturers do things at times) that their is a very cheap universal chip type tuning system in play here on the order of about 10 cents value that many manufactures are probablly incorporating these days. What I did to solve this annoyance was to purchase (after many tests) a SHARP brand walkman type AM/FM hand unit that has really good AM and jack it into the preamp section before my crossover (added an extra input via Y-adapters) and use Ni-metal-hi batteries that can be recharged. I get about a week out of the 2 AA cells. I also had to build a rather good cable (shielded) to go from the unit to the 1/8 jack to cut noise a notch more. This has proven a good situation for me.
With this knowledge, I wonder what head units actually have good rejection circuitry and great gathering power for amplitude modulation?
