My 98 has a cassette Radio. (U!L) No Bose. 6 speakers AW6
I would like to put in a radio with a CD Player or remote changer in the trunk
Is there an existing cadillac radio that will drop right in?
32 Pin connector
I am 98% sure I have seen a 98-99 non-Bose cd, hu for caddy in my junkyard trips. Probably pretty easy to find on eBay. I also think u can install factory cd changer on your system. My car has Bose, cassette, trunk cd changer.
There is a similar (if not identical) thread on the same page.
If you have '98 with only cassette player (no InDash CD) then you have base sound system.
YOU CANNOT ADD INDASH CD TO A BASE SOUND SYSTEM!
I know they look the same and you are tempted to say "heck is from the same car and year, must work". Let me stop you right there and perhaps save you some money and frustration. The HU you see with InDash CD are for BOSE sound systems. You cannot imagine how much different the 2 systems are (yes the connector is the same and mounts perfectly in the dash) but that's about it.
Let me tell you what it will happen, you plug it in, you do the VIN clear procedure (let's not get into details and money figure what that involves) and the new HU will turn ON, you actually have control over it (clock, all displays, volume level display, basically everything) but you will have NO SOUND, not even chimes.
The BOSE sound system involves extra module/relays, 4 amplifiers and 4 different speakers with enclosures, and a complete rewiring of the entire sound system (every single wire with in the sound system must be replaced). The cost of doing all that (if you find a qualified technician) will pretty much be similar with the value of your car.
The best news for you, yes there is a good news, with less than $100 (probably less then $50) you can add a 12 Disk OEM CD changer. It mounts in the trunk and the car is already pre-wired for it, all it takes is put in the 2 bolts to screw the bracket on the trunk floor (all holes available) and then connect the cable (is tucked away in the power antenna area underneath the trunk liner) and BAM instant CD player.
The HU will recognize the CD changer and a new icon will show up on the screen. Now when pressing source you will have Radio/Tape/CDChanger.
The HU is designed to control fully the changer (including steering wheel controls). The key is to get a OEM unit not some aftermarket crap that is actually radio and requires a controller.
These OEM changers are easily available on EBAY or local wrecking yards for next to nothing. Just ensure it comes with the disk trays and the bracket (specific to Cadillac). The CD changer was used in Corvette, some Pontiac/Buick and other similar GM vehicles (and the bracket is not the same).
This is what you need:
The connector and harness shown above is already in the car.
