Hey guys, just had a question about the reverse parking sensor display. I've seen inside the is250 manual that a display pops up showing the sensors are active. Just a couple of questions: 1. Is this display in the "NAV" unit, or in the little screen between the speedometer (since the picture in the manual makes it look like the sensor is in the latter) 2. Does this display pop up for everyone with reverse parking sensors (lexus fitted)? (i'm just asking because i have reverse parking sensors, and i don't have the display when i reverse) 3. Is there a way to tell if my reverse parking sensors are lexus fitted? I bought my beloved IS250 Prestige second hand, came with lexus sunroof, aftermarket HID, and these reverse parking sensors which don't have the display. Cheers. Twisties
