Does anyone know if I disconnect the battery and for how long would the phones saved to my factory blue tooth be erased in my 05 LX470? I didn't erase them before I did stereo work and now the access to delete it is no longer available and it keeps trying to pair with my phone making me nuts. About to break down and get a new phone but was hoping someone might know if disconnecting the battery would work and if any idea of how long it would need to sit.
