battery advice

I’ve tried one of those memory holding cables on the Z. Didn’t work. Just put in a new Bosch Platinum AGM battery and reset your radio. Our car only holds 6 stations...

The memory retention things that plug into the cigarette lighter won't work on our cars, the ignition has to be on in order for that outlet to be active, in fact, 95% of Honda, Toyota & Nissan's are like this. External power applied to the OBDII port will allow the ECM to retain all settings. I did this when I swapped the battery in my 2012 and didn't lose anything.

Correct. I have one for ODB to a cig lighter, and plug it into a power pack, or nearby vehicle. with the 5 vehicles we own, its a huge time saver as opposed to trying to remember what I need to reset in each one, let alone the steps to do so. (2 Nissans, an Audi, a Subaru, and a Chevy)
I think I paid $25 for it. Would have paid double that for the time I save.
