Hi,

I recently had to switch out a dead battery on my 2007 Rx 350 and I think somehow i managed to blown some fuses.

So far I found my driver side window controls are not working except for my driver window. all other 3 are not working (not locked). However the passengers own window control is working fine.

My Nav said exteneral device not connected and the menu botton on the nav isn't working as well. So far everything else appears to be working fine.

I checked the fuse box under the hood and under the driver side and dont see anything blown or burn. I did randomly pulled like 5 to 6 of them to check and everything appears to be ok.

Is there another fuse in the truck or behind the nav system? anyone could help me out on which fuse i need to change?

Thanks greatly appreicate any assistance.

I'm not sure about the nav stuff, but your windows need to be reset after a battery change. Look in your manual for the procedure to fix the window issue.

My guess is you need to do something similar with the nav, but I can't help you there.

Hope that helps.

Did you pick the correct group number for your battery?

I hope you did. Last week, i was helping a neighbor who tried to switch out his old dead battery for a new one in his late model Toyota. He did not have the correct group number size, so the battery terminals were swapped. When he hooked up the battery, it blew a handful of fuses and would not start. After, i pointed out his battery was wrong, he bought the correct model and we installed it.
Apparently, the wrong battery caused damage in the ignition system already and it was too late.
He is currently shelling out more money because of his battery mistake. Of course this was a worse case scenario.

Battousai, the window and sunroof reset issue after a battery change has been discussed plenty of times here at CL. You can do search. It is also in your Owner's Manual on page 41.

I got the battery from Napa and even show them the old dead battery too. My car runs fine and ok, everything is ok except for the nav and the windows.

Does anyone know how to reset the windows? and if needed resetting the Nav?

Thanks buddy, The sunroof is working fine

I will try out the window reset to see if it will work.

Now i hope on page 41 will have something to reset the NAV. I dont want to take the NAV out from the back panel.

Already fixed the windows issue, however I still got the nav unable or don't know how to reset it. Any help? Thanks

I would follow the instructions which follow to eject the DVD disc from your vehicle, start your RX without the DVD to cycle the system, then shut off your RX and reinsert the DVD. Perhaps this will help reset the system.
