OK so i have been ahving problems with my navigation system in a 2005 TL... first off the display buttons went out, the "off and dual" lights... anyways not a big problem simple $100 fix... but the real problem is i did a reboot by going to version under the diagnostics panel and now i cannot change any of my audio setting ex. subwoofer anything along that nature... the only options i have now are treble and bass... i have the original orange disk that is given to you with the car... i was wondering if there is anyway to go back to running the edition of maps i had before?? any help is greatly appreciated!!

 

before it was starting to re boot on its own so a friend of mine suggested me to try taking the disk out and cleaning it and then re booting the system... now this is what i get an older version than what i have been running in the past that is not as nice looking and does not have nearly the same functions... one difference i have noticed is that it used to boot up with the acura logo and now it is the honda logo at start up...Please help!!
