Thank you for the order.. The system works fine.. easy installation... Recommended for buying. once you turn the display on,and see 4 tires pressure.. Never turn it of on the display with the same knob you turned it on .. Once active and turn off,and afterwards turn on ..The display has to search connection with all 4 tires again,and with bad luck it misses connection wit one or 2 readings of the tires. These are already programmed,otherwise the display gives unaccurate readings . When buying this product. install all components. Turn the display on..If it sees 4 values of tires.. don't play with the configuration knobs of this display, If you change confiration.. there is no manual how to get the changed settings back as before. ..
All OK!
