Music system i have got the original spec radio,cd player & tape deck is it easy to replace with another up to date one ?

Unless the tape deck is a separate add on I suspect that it is not a fuse problem. Interior Fuse Box Location 1999 2003 Acura TL 1999 Acura TL 3 2L V6

Try cleaning tape deck with one of those tapes that cleans the head in the tape deck.

if its a radio shack radio, it means E13 means "Tape Communication Error". It is caused by the
microprocessor reading speed pulses from the tape deck either too fast, most other makes mean about the same thing, normally a stuck tape will cause this code to show up, either that or the drive gear that loads and unloads the tape is broken, cracked, or jammed

It's the tape deck there must be a tape that got caught inside and is wrapped around the capstan or the heads and the radio stays on because the switch is not activated by the deck lowering down far enough you have to take it out and clean it and look for any tape or other obstructions that would stop the mechanism from working including the belt you may need parts and a 20 year old radio there hard to find try the junk yard for a replacement but you can operate yours with the cover off if you can get it out far enough to see inside while it's on and that will help you find the problem but first bring it inside your house so you don't loose parts after cleaning with alcohol and derusting if any and a light lubricant you might be lucky see what happens I also use an adapter for my cell phone music in a 2007 bull and I also did it in an 87 bull with a cd player so I know what your talking about also make sure the adapter wire is not hanging up when pushing it in good luck also brand new replacements might be the best way to get the music you want they have auxiliary input jacks for cell phone mp3 players but try to fix yours first the learning part is priceless for the future radios you will own

Instead use a radio adaptor where you would set you radio to a particular channel. The adaptor emits a signal correspondent to that radio signal and allows you to listen to your iPod.

I could go outside and pop my dash apart real quick and tell you.Its real easy to take it off and pull the cd player and radio right out.Is your wiring harness missing or something?Is that why you need to know what it looks like?

ok... the 98 corolla (that i know of) only comes equipped with the tape deck and radio, you probably have a after market radio, these are easy to replace, you can buy any standard cd player to replace yours, even if the wiring harnesses dont match up right, i offer a diagram for the colors and labels on my tips, its fairly easy to do, check it out and good luck!
