So I've read a few threads on upgrading stereos from older Priuses, but I'm not sure if they apply to the Prius V as well. Unfortunately, my dealer gave me faulty information and told me that it is possible to get satellite radio on the car --- but as you all know, the Prius V Two is not satellite ready. I'm also pretty disappointed with the sound quality of the unit, so basically I'm looking for the best upgrade(s) for sound quality and to add Sirius/XM radio. Any suggestions? I'm thinking that I might have to wait for some OEM accessories to come out for the V, but since I'm a brand new owner, I figured some of you might have better solutions! Thanks.
