HY!
many years ago, i see the panasonic radio in a test in a car&hifi magazin and i was MP3, front/rear(sub out and Line In, Touchscreen with 1 million colors, very good sound and many more, but the new price was 800 euros!
The new price was 800 Euros! :( i found the radio on ebay.de for 460 euros from a car-hifi-shop and bought this radio. 2-3 years, i have the radio with the normal single-DIN- adapter in my IS. But the look was not lexus-like. i become a defect original radio and installed the panasonic dispay in the original frontmask. i search the contacts off the buttons on the print and the conducting paths for the led´s to combinate to a group and set the brigthness to original with resistors. The buttons connectet i to a original panasonic remote control and installed the IR-LED to the IR-receiver beside the panel. its read very easy, but its a hell to find all connections and hubs on the prints and connect correct for the funktions.
here pics from the conversion:
the first test:
i need more paint-session to have the correct surface. Its RAL 9005 matt, this color is perfect for frames, gauge pods....
the time, that i needed to finish complete this radio with all problems in the constructions-time, maybe 50-100 hours, or more
