I'm in a situation where I have the Blu Logic kit (PT923-00097) and a t9200 CD player coming from eBay, and a Toyota Y adapter (08695-00370) for between the rear of the Multifunction/Radio to the CD player and perhaps Blu Logic. I was wondering, is there a way for me to have both hooked up at the same time perhaps to a switch that I can switch between the two, or do I even need a switch? Down the road, I might want to replace the factory CD (T9200) with some other headunit. I already have a 2 part factory harness cable (TWH951) that I hope to use somehow as well, if necessary. Gen 1 Prius,2001 base, no nav/CD. Thanks everyone!
