After market stereo
 

Hoy all,

I've decided to install a after market stereo in my blazer. In doing a search at Crutchfield, I put the required info in for the vehicle and there are two choices for the two door Blazer, with or without the Bose system. I called to find out what the difference is. Apparently the Monsoon (Bose sys) has a signal processor that Crutchfield hasn't researched.
The previous owner had put in a after market stereo, but it was stolen. He sold the factory installed unit before the stereo was stolen. He then replaced it with a Monsoon from eBay. So I don't know what was original. I've decoded the RPO's, and have codes UN0 > RADIO , "AM/FM STEREO, SEEK/SCAN," and UP8 > RADIO , "PROVISIONS, AM/FM STEREO, INSTRUMENTATION". Does the Bose sys have a different RPO #?
Any help with what I've got, and what can go in place for the factory systems will be appreciated.

I found it after changing and adding words to a google search. Y91 is the RPO code for the Bose sys.

if ur looking to just put back in the factory radio it will be kinda expensive to get one. but as far as aftermarket radios u can put in anything. if u buy it from a store like best buy they will help u get the right stuff to install it urself if u want its pretty easy. all u really need in addition to the aftermarket radio to connect it is a wiring harness, antenna adapter, and bracket adapter kit.
