Hi, I have a 2002

Hi,
The Lexus Link system was abandoned in 2004 due to the systematic shut down of analog cellular phone services. The Link system is strictly analog, and when the FCC directed a transition to all digital for cellular providers, this let the Link System inoperable.
When the Link system attempts to initiate service, it can not and results in an error.
While it is possible you have additional issues, it is rather unlikely, and you will never be able overcome the missing service error.

In March of 2004, Lexus began removing the systems from customer vehicles free of charge. Unfortunately the dead line to have this done as a free service ended in 2007.
You can still have the system removed/bypassed in the same fashion as the temporary recall campaign, but are responsible for the costs incurred. The cost is typically $150 to remove the abandoned hardware and eliminate the voice message error.
You can refer your local dealer to:
* Campaign LSC-4LA - Campaign - Lexus Link(R) System Removal

Regarding the bluetooth upgrade, there is no later model unit that is compatible that you would be able to swap out unfortunately. You will need to go with a third party adapter such as Parrot in order to have a built in bluetooth system.

yes unhooking the battery should reset the error. if you have an anti-theft radio make sure you know the code and how to enter it. unfortunately for your second question i'm abit weak on solving bluetooth setup.
