2001 Prius; Is there a radio / Dash upgrade I can install that has the touch screen, Bluetooth w/e? What would work best?
Just find one that will fit where the CD player is. Identify the wires on the CD side pigtail and cut them. Wire your new one in using the CD pigtail.
Looks to me like a DIN 1 would fit in the little bay for the cd deck Bluetooth is possible, touch screen on a din 1, not so much. One thing I wish Toyota had done is to go way more conventional on the sound system--tho it is acceptable for a factory radio and cd.
Din 2 fits fine. Did a cheap Chinese all in 1 unit, been about 5 years now no complaints really. Thinking of upgrading to a newer unit with Android.
If you don't have a factory CD player, you'll need a pigtail. I have a spare I'd sell for $15 plus shipping.
