Using a Battery Tender for Nav Updates

[Gottogofast]

Has anyone used a battery tender instead of running their engine while upgrading the navigation system?

I feel like the bigger problem is the on timer timing out and shutting the system off in the middle of the update. Otherwise, it's very unlikely that having it in the accessory position for a couple of hours would run the battery down too much.

Yep, just take a nice hour ride, get your wife an ice cream. The radio won't work until done so you can even talk to each other.

I thought I read that someone just shut off his car and when he got in it the next day, the update was completed. I am too scared to try that so I just ran my car in the driveway for about 1/2 hour until it was done.

Oh, no! You wouldn't want to do that!
