Just traded in my 05 SL55 for a 09 SL63. First thing I noticed is that my advanced tire pressure monitor on my SL55 that gave a digital readout is gone on the SL63. I don't know about you, but I used that all the time. Is there anyway to upgrade back to this feature? Secondly, is there anyway to adjust the sensors on the bumpers for the Parktronic feature? The system does not detect the Jersey blocks that are usually in all parking spaces. I guess they are too low for the sensor but not too low to ruin the front bumper lol

Thanks,

George
