I have a factory 6-CD changer (trunk unit) on my 92' e34. It takes forever to read CDs (not orignal, but the ones I burnt) or it skips a lot. It reads one CD today, but it wont read it tomorrow. Now therez one thing I noticed that it wont read any CD at all during daytime in summer days (now that its getting upto 90 also), which it will read in the night when itz cooled off. So I am guessing therez something to do with the old electronics on the player which doesnt work properly when itz above certain temperature. I wonder if the capacitors or dielectrics which may function differently at higher temperatures.
So bottom line.... is there any way to have a cooling system for a 6 cd changer (trunk unit)?? Has anybody done this before? What would be the best way to do it?
Fans wont do much, since the air in whole trunk is heated. SO I am thinking lil fans wont be able cool it much.

BTW I have model: TR1001 (made in Japan)

Given the age of our cars, the technology wasn't there for reading burned CDs. If it works fine with original CDs, then there's probably nothing wrong the the player. I did read on another forum that sometimes CD players are more finicky with certain brand CD-Rs and often don't read CD-RWs at all. Try another brand and see if that makes any diff.

i sometimes have this trouble with my home cd changer where it takes a bit longer to load a disc

i seem to have solved this problem, and you may want to try this

When burning your cds, choose a lower speed for the burning process, like if you usually burn at 20x, try 12x. it seemed to work for me.

My old burner wouldn't make the CD's playable on many older CD players, when I got a new one in my laptop it worked just fine. It could also be the program you are using to burn it....just a guess haven't tested it...

thanx for replies guys.
Yes, I do burn my cds at lowest possible speed. I also noticed when i burn it at 4x it actually goes to ~8x. I am using Roxio easy cd creator v7. Also itz better if you close the cd instead leaving it open.

As I said before, it reads the same cd in the night when itz much colder without any skipping. But it refuses to read any CDs during daytime when itz freaking hot. You can feel the heat if u touch the cd player in the trunk. Very very hot.

Older electronix doesnt work well at high temps. So that was the reason I was trying to figure out if i can put any cooling system on it like on harddrives or Cd-roms in pcs.

copper coil with water circulation would be pain in the ass, but fans wont do any good.
Any suggestions?

1) where to get power for fans from??
2) Its really way too hot for any lil fans to cool it off. If you also have trunk unit, try touching in the afternoon .

physics....damn physics always gets in the way.

Mr. Hire, think about it. Cut a hole in your trunk, attach a pipe so the air will flow from the outside to your CD player?

Install a small cooler in your trunk to turn it into a refrigerator?

Cut a hole in your back seat, install pipe in your back seat so the air from your air conditioner will cool the trunk?

Or maybe you can install an ice holder an put some dry ice in it when the temp goes above 85.

Maybe install some double thick trunk insulation along with cutting a hole in your back seat to the cool air will flow to your CD changer.

How about buying a new CD changer....prolly would be cheaper....and easier.

I dunno....anyone else with an idea?

update: install the CD changer in your glove compartment.

Thanx a lot silver4evr
You cracked me up for 5 min tho :

I aint cutting any holes in my bimmer. SO all suggestions with holes not good. sorry.
Ice holder with dry ice? wonder who could make me that particular shape and would it be physically possible to contain the temperature.

Changing CD changer is a good idea which involves ~$500...I am still a grad student cant afford right now.

Thanx anyways

Try this to cool it off.
you'll need to modify your cd changer by adding a heatsink unit. Heatsinks are use to cool off enclosures that run hot all the time, they vary in size, they have fins.
You could buy one at an electronic shop.

1. cut a small rectangular opening on your changer.
2. mount the heatsink on the opening using short sheet metal screws.
3. you're done
