QuestionI have two faults with my BMW factory fitted (2002) Radio Model PH7050 & BMW fitted 6 CD changer;
#1 When using my Radio (on FM) I loose my FM reception if I switch on my rear heated window (rear winscreen). The AM reception does not seem to be affected. When I switch off the REAR window heater the reception comes back again. Fault only happened recently (reception dropped to zero when I was listening to FM radio when the rear heated window was being used)- worked ok before with the heated window switched on. (Could fault be connected with built in radio aerial amplifier - aerial is built into rear windshield / part of rear heater window element?)
#2 Fault with my 6 CD changer (which is fitted in the boot)appeared two days later. The CD had been working ok the day before I noticed the fault. The next day when I tried to use the CD it would not work; indicator showed "NO DISCS" although the cassette had 6 CD's fitted.
I removed and tried different CD's but fault was still there. (I also checked CD's and checked they were fitted correct way up).
I now notice that when I re-insert the CD cassette into the changer it does not seem to go through the normal electrical/mechanical CD check sequence (previously noticed the platter 1 -6 sound when it went through this check).
Answer#1: Yes, I think something is causing the fm antenna amplifier to lose power when the window heater is on. This can be verified easily if you have a voltmeter and measure the voltage on the line to the antenna works. OR, you can take it to a good car audio repair/install shop who can quickly check it out.
#2: I think a reset may cure it, but if not, have the shop check it out when you check out the fm problem above. To reset it you must pull the power (plug with all the cables will do it) so that complete power is removed for about 1/2 hour, then repower it. If it does not solve the problem it may be time for repair/replacement. Generally repairs are expensive, so much so that replacing the unit may be a less expensive route.
Finally, there are aftermarket interface units that allow you to connect your iPod or mp3 player into the head unit; this is the way many are going nowdays. Just an idea. Sounds like a good idea, doesn't it?
