No AM reception for car radio...do get FM reception.
I was having the same problem with a jvc kd hdr 30. I Installed it myself over a year ago and never wanted to deal with the issue. Finally, I decided to take a look at it today.
On my head unit, all wires were connected except one blue one with a tag that says "do not connect to power, for remote device or power antenna only." This unit is in a '97' MBZ E320 with no visible antenna; I think it is part of the windshield. In any case, between the wiring diagram in the manual and the harness that is part of my car, I was left with 2 blue wires to choose from, one with a white stripe and one with a gray stripe. After testing both for power or ground, I determined neither had power with key on or off. Both had high resistance ground when compared to the chassis ground. In other words, I measured between chassis and these wires. First, I took a wire and connected it to the chassis ground and connected the other end to the blue wire coming from the unit while tuned to a local am station. This simply killed all reception am or fm but did not harm the unit. Next, I connected the blue wire with gray stripe of the car harness to the blue wire of the unit and again this killed all reception. Then I connected the blue wire with white stripe of car harness to the blue wire of unit and presto magic I had great am reception.
I am guessing that this blue wire with white stripe must be part of the antenna itself or perhaps is a connection that increases antenna power. Maybe 'power antenna' on tag refers to an actual powered antenna (like as in amplified?) and not as in an antenna that rises up out of fender, as I believed.
This may not help the first person with the question, but maybe it will help someone out there who searches for these kinds of answers like I do from time to time.
How to install sterio on a 1998 cheavey sierra
Did you cut the harness already? If not, get an adapter from crutchfield or metraonline website. the adaptor plugs into your car and the other end color matches exactly with that of JVC
How do i get my cd out its stuck when i push the
A trick I've used several times is to hit the eject button and take another CD, put it in about 1/3 of the way, push down on the CD that's stuck inside while pulling forward, all of this while the deck is trying to eject will usually get a stubborn CD out.
I believe i may have gotten some water in my JVC
If you have not put on the set after the water logging then you could have been saved. Now there is a chance that the processor section have shorted circuit. please open the set, use a hair dryer and warm up to clear up all the moisture. use petrol to clean the main board do not put any petrol on the main panel or plastic.but only the PCB. after cleaning heat again till you have warrmed up and cleared all moisture. reconnect the set and test. I hope this must clear your fault or else you will be having faulty componentts that needs further continuity and voltag checks for finalising. hope my advice helps. good day
Car stereo install
Get your hands on a good wiring diagram for the vehicle, preferably from the dealer, find applicable wires (and color) on chart.
Then get said head unit, either in the manual for it or on the case of the unit there will be a color-code chart, match colors and/or wire functions (ie., POWER to 12V constant).
You should ALWAYS use a remade wiring harness, every professional does unless its a true fabricated install, but this method works also. Remember, the wires are already existing in the car, all you really need to do is identify which is which and hook them up to the head unit.
PS: make good, secure connections; no half-assed electrical tape jobs.
