I would expect the nav system to not loose its memory. The Radio on the other hand will go the way it goes... Some radios will save station presets some will not.... Mine I know for a fact does... so does the one in my boat....

As for any of the work arounds here, etc. that I keep reading... I recomend none of them... No offense guys... but the link for using a secondary battery in parallel??? that is asking for a problem, and with the electronics in the cars today you are asking for an even bigger problem.... As for the 9V solution... I would like to understand more about this? but quite frankly I think your fooling yourself thinking that a 9V battern is keep your memory alive....
