Default Playing cassettes on car radio CD systems

I have a new car with a CD autochanger instead of a cassette radio whic
cannot be fitted because of there is an integrated SatNav system whic
needs a CD player. I record cassette tapes off home radio and want t
play them in the car. I have tried an Arkon Sound Feeder which uses
walkman cassette feeding into the Sound Feeder which then sends a F
signal to the radio. The radio needs to be tuned into an unuse
frequency.

Could I record onto CD's instead? Tapes give me 2 hours each; CDs onl
give just over an hour.

Problems a
(1) Sound Feeder solution is messy with the walkman and the soun
feeder wired together and powered from the 12V socket and usually end
up on the passenger seat.
(2) Most of the the FM channels are used so it is difficult to tun
in.
(3) The frequency control onthe Sound Feeder to tune in to the radi
seems to drift and needs occasional adjutment.

Ideally I would like to install a separate car radio cassette (o
cassette only if available) feeding into the pre-amp via an auxiliar
input of the factory installed system. Otherwise an input from
walkman cassette, again into an auxiliary input on the installe
system?

Anyone got any solutions

Let's see if I can help you with some of your questions:

> give just over an hour.


CDs will never give you more than 80 minutes of recording time because
their data-stream playback rate is fixed. You could cram twice the length of
recording into a CD, but it would play exactly twice as fast, making
everything sound like a chipmunk because the player will only playback at
one data rate. MP3 players can vary their player playback rate which is why
they are so handy, cramming TONS of crap into the same space using fewer
bits...CD players can't, sorry. :/

You could try cramming the sound feeder inside your console (if you have
one) by prying out the snap-fits on the console panels and laying the unit
somewhere where it won't interfere with the transmission shifter, etc. Then
just have the power wires protruding out somewhere less visible with the
power connector on the end (near the cigarette lighter probably).

You could try reading with a multimeter the exact resistance of the
potentiometer (frequency control) inside the sound feeder with the cover
removed (first you'll want to get the best possible frequency by listening
while tuning the dial) , then solder in a resistor pair that matches that
resistance as closely as possible in lieu of the potentiometer (remove the
dial and put in these resistors instead).

Or, you know, just put a dab of hot-melt glue onto the dial when it's
adjusted right. =)

Find which wires in that changer cable are the audio L and R, then cut
them. Then: 1. solder the end of the audio L nearest the changer to a
double-pole, double-throw (DPDT) switch contact, the one NOT in the middle,
and on the left side of the switch. 2. solder the L audio signal from the
walkman (get to this signal wire by cutting a headphone wire pair + jack
from a pair of cheap headphones and stripping the loose ends) to the OTHER
contact on the switch on the same side , NOT in the middle. 3. solder the L
audio wire from the changer cable nearest the head unit to the CENTER
contact on the switch on the same side you've been soldering to. (this way
you'll be able to switch between the cd changer and walkman at will) 4.
repeat this for the right side of the switch contacts, keeping the
orientation of the switch contacts consistent for each audio signal you tap
into.

Lemme know if this helped!

There are some new technologies that are quite a bit better sound quality
wise than what you can get with tapes and FM transmissions. You may wish to
buy a head unit that plays MP3 formatted songs and burn CD's with those MP3
songs (you can even use on some head units read/write CDs (CDRW) so that you
can burn a cd and later change what's on there). With high quality
selections in creating MP3 songs you can usually get around 100 songs on a
CD - maybe around 3 hours. I burn my mp3 cd's organized by artist and on an
Alpine CDA-7995 for example one touch of a button moves you along from one
artist to the next, or another button moves you sequentially from song to
song. Also, random play within an artist group or across the whole 100
songs is possible. Last, with ID tags that are part of MP3 format, some
head units will scroll that ID tag across the screen so you see a text
message of the artist's name/album/song title. Great fun, and sonically
miles better than tape.

Try this. 'JVC FM modulator' (http://tinyurl.com/vuf8)

You will be able to use a portable cassette player or walkman with it.
Has 8 frequencies to choose from, hardwired and should not drift like
the transmitter units. Since you want to keep your existing factory HU
due to the satellite navigation system, this may be your best choice.

Since you primarily use cassette to record off the radio, have you
considered getting a minidisc recorder? Much better SQ than cassette,
and if you use LP2 or LP4 recording you can squeeze an huge amount of
audio onto a single MD. A single 80 min MD will get 320 min at LP4
recording.

Thanks for replies - my use of cassettes is for temporary radio play
and other programmes so use of cassettes is ideal because they can b
easily re-recorded when listened to (sorry Derek).

Thanks anders, I could play around with linking in to the speake
wiring but it is a lease car and wish to minimise any mess as it i
very definitely frowned upon! But I may resort to this. Reworking th
SoundFeeder with a fixed resistance is a good solution so I may yet d
this.

Thank sneezer, looked at the JVC FM Modulator but similar problem i
that in needs physical connection to antenna. I am unwilling to loo
behind dash until I am sure of a solution that will not mess up th
factory installation.

I am hoping that there may be a proper auxiliary into the main unit.
do not even know what make this radio/audio is. The car is a U
Citroen C5 and with the SatNav it will most likely be Bosch?

Thanks for the replies. I have not given up yet.
