Is Radio code required?

[wanted Member Find all posts View Profile Close wanted]

Hi team, time for a new battery for the 150 (late 2014). Cannot seem to find the code anywhere nor do I remember if I have every used it. Reading a few older posts mention the 150 does not need the code anymore just the Jam function needs to be reset. Can some one who have replaced battery confirm this? How much is the dealership going to charge in case a code is required. Not having driven much has definitely caused the battery go earlier as it seemed to be doing fine before the lockdowns! Thanks.

I have disconnected the battery several time over the past 2 years on my 2016 GX with no effect on any system when reconnected. From memory, the stock radio head takes a little longer to boot up when power is reconnected. From then on, it's back to normal - all presets etc are remembered.

Thanks GeeWhizz, I hope this is the situation. Reading other stuff is a bit scary in terms of ECU forgetting its setting etc. etc. I assume that you do not have the 'code card' in your service booklet or your user guide either. Did you have to reset the Jam function or not even that? Thanks.

As GeeWhizz says.
I have disconnected the cranking battery many times. The head unit will re-boot on its own, but you mite need to reset the clock.
