Amazon has several Tyto-01's that come up when you search, but none seem to say that they are compatible with 2009 Prius (w/ JBL/Nav). Any ideas? Can I use the one for 2003-2008? I plan to buy all of the parts, harnesses, etc. as part of my quest to find someone in San Diego to install an aftermarket stereo. My impression from these forums is that Tyto-01 is needed. Thanks for your help!
If you search the meter catalog (Metra Online | Welcome to Metra Auto Parts Online Warehouse) you will see several things listed however there may be things that are on there twice and things that your particular car may not need. The last time I called their tech support they were very helpful. I would suggest you call them as you have not gotten any replies so far.
