fix for ipod problem?

I'm really disappointed in the IPOD interface. I bought a new nano, just for my car. The Prius owners manual says they work together. It also warns me not to leave the nano in the car, due to the possible damage to my ipod by heat. Heat? Are you kidding? I think the cd's loaded into the dash for the GPS are way more delicate than my flash drive nano. If I follow their instructions and disconnect my ipod every time I get in or out of the car, one of two things will happen.....either the usb jack in the car will wear out, or the multi pin jack in the nano will wear out. Either way, they are not made to be constantly connected and disconnected. But since turning off the car, cuts the power to the nano, if I DO leave it connected, the nano loses it's mind and must be rebooted each time.

SO, I need to find a place to rewire the car usb jack so that power is not terminated to the nano, when the ignition is shut off. This car is great, but the nav unit is so poor, as I've complained before, that sometimes I wonder if it was even made by the same people who built the car!

 

Thanks Ed. Well today I bought a short usb cable extension (male to female) and plugged the ipod cable into it, then the extension into the car jack. So now when I stop the car, before turning off the ignition, I just pull the two cables apart. Then I turn off the ignition and turn off the ipod. I am still thinking about finding a company to wire the usb so that it always has power. Not really concerned about running down the Prius battery charging the IPOD. That would take a few months! I also read that the red cable supplies power in a USB cable, so I bought a few to see if I can splice a switch inline, to just "click" off my ipod. But that solution would still require me to turn off the ipod every time I get out of the car. Anyway, I'll post my findings.
