Hello, I have a Toyota Prius 2011 Non-JBL Factory Navigation System (Part Number: 86120-47290) and I would like to upgrade to Toyota JBL Factory Navigation System (Part Number: 86120-47390). However, I do not have the subs/amp. Is this possible to do without the sub/amp? Did anyone try to install a Toyota Factory Navigation System on a non-Factory Navigation System? Also, I’m open to any other advice / comments / suggestions / solutions! Thanks AB
You'll definitely need the GPS antenna also. Upper dash off to install it. The JBL system relies on the amp under the passenger seat. I think it also has a different number of speakers, but you might get away with leaving one set of outputs unconnected. The wiring diagrams are at techinfo.toyota.com. I predict you'll be looking at them. -Chap
Honestly its not a fantastic system for the money. Buy a small amp and some decent speakers and match it to one of the new aftermarket navi's with apple car play and what not.
