I have a Prius package IV with the JBL stereo and have just purchase a NAV unit from another 2010 prius and was looking for some info on what I may run into with the install. Are the wiring harnesses the same? Where can I get a GPS antenna? Any help is appreciated.
Prentp, The wiring harness should be the same but if you want to play it safe you can get the Metra 70-1761 Radio Wiring harness for about $7.60 from Amazon. I'll let you know when I pull the unit if the GPS antenna comes with it - I'm thinking my new aftermarket HU will come with a GPS antenna in which case I should be able to send the OEM antenna with the unit. Will keep you updated but if anyone else knows for sure, feel free to add your expertise!
