On 12/21/20 I went to the lexus dealership located in Rockville, MD for a bad battery. I jumped start my battery and started heading to the Lexus dealership in Rockville, MD. Grant you everything was working fine except Navigation screen now. It was now displaying on the navigation screen " A program can't be read. Please consult to a dealer." My CD player, radio and Heat was working while heading to Lexus dealership in Rockville, MD. Once i arrived there my service advisor was Omar Pacheco had my battery replaced cause it was still under warranty but then informed me that i needed a new Navigation Hard Drive which would cost me $2778.94. I stated to Omar why do i need a new Navigation Hard Drive? I've had my battery changed in the past and didn't need a new Navigation Hard Drive. I later found out from one of the mechanics while i was waiting for my car (07 Lexus LS 460 L) that my Navigation Hard Drive blew out due to the fact that when they changed the battery they was Not suppose to turn the car completely on until the Navigation Hard Drive was finished loading (Wow). I've would've came in sooner but due to covid-19 and me having type-2 diabetes it's been ruff. My name is Joseph Morgan P.O. Box 705 Germantown, MD 20875 Tel. [protected] Email.
