All. My 2004 got the RTOD, so I downloaded the DRPRIUS app and purchased a cheap ELP327 off eBay (before reading I shouldn't have done that!). My BT connected with the app and I was able to clear the error code. However, the app shows "no data" on the main screen. The multi-display shows the battery is charging/discharging. Did I buy a junk OBD2 reader, or am I doing something wrong with the app?
