Just found a hidden service menu in my 09 Pebble Beach Edition

Guys, I just found a secret service menu on my new 09 PBE. This might be just the old news but really cool. Just surfing the internet and happen to read the info on another vehicle. Tried on my and it works. I can display the speed sensor from GPS and compare to the speedometer and turned out mine was reading about 7-8% faster. Last time I usd the community speed sensor and it said mine was about 10% faster. I can display both in KPH and MPH. I brought mine to the dealer last month to calibrate the speedometer but they tested out and said it was OK. Planned to buy handheld GPS to bring to them next time.

I can't find the NAV override option. There is option for bluetooth that you can raise the mic level. Be back in a minute. The wife is calling...
