My 2006 IS350 would starts fine and when i pull out of the garage my nav screen along with the buttons on the side (map, audio, info, etc...) will restart... i stop put in park, shut the car off but wouldn't start again... then i try again but only goes into accessories and thats it... but like after a few minutes it starts fine like nothing was wrong... i cleaned the battery terminals but same thing still happens no warning lights to begin with and no warning lights now...
