RX in the garage for a month...
We went on a post retirement cruise/road trip and our RX was in the garage for a month without being started.
I had remembered something about having to use the key after the car sat idle for so long but it unlocked as I grabbed the door handle.
I have noticed some settings seem to have reset in some way. When the Nav system started up it said something like loading from the DVD and all the track history was gone. We went on a trip today and the NAV system indicated a much longer travel time and I wonder if my adjustments to the highway and freeway driving speeds have revered to the default. Now that I am writing this it seems the resets I have noticed are all related to the Nav system. Is there anything else I should check or a list of known things that need to be reprogrammed after a month of no operation?

Could you do me a favor that check if your trip computer A and B reset? I have this OCD thing where I like it to be never reset, and I just came back from a 3 week vacation and found out that they reset at some point. I asked all the drivers in my household and nobody claimed they reset it, so I wonder if it was from the long trip.

That being said, I'm not aware that you should loose settings of any sort assuming of course your RX350 battery maintained sufficient charge the whole time. While it can be debated and is dependent upon many things, other threads indicate that 4 weeks could be on the edge of where a locked and unused RX could have lost enough of it's battery charge to kick-over -- how that would apply to loosing settings somewhere, I can't say. Do a few searches if you're interested in those other discussions as to what others have done when they need to leave their RX sitting locked for extended periods. FWIW, I keep a "battery tender" (many names for those sort of devices -- not wanting to get into a technical debate on them here
) on my SLK when it may be sitting for several weeks in my garage as a preventive measure, and never have an issue loosing settings of potentially having a ride that won't respond when I try to unlock and start it.

Not really. The battery will continue to drain regardless. To me, it's a question of how much, how fast the battery looses it charge... and of course if one cares about having the vehicle's security system engaged (which I do, even in my own locked garage). It's why I put a "battery tender" on my 2nd vehicle if it's not going to be driven for a few weeks, and when I used to travel extensively on business, if there was a potential of my ever being gone for 4 weeks or more, I never left my car at the airport where I would potentially come back to a dead battery late one night when I was dead tired and still had an hour drive home...
