Hey everyone,

I have a 1998 GS 300 with navi but it doesn't always turn on. Sometimes when I start the car it will turn on and I can use all the features but most of the time I just have a white screen and have to randomly press to change things. I can manage it a little but I would like to fix the problem. The keyless entry also has some problems. Sometimes I will hit it, the horn will sound and the alarm will arm but if I pull the handle the door will be unlocked (one or more doors). I've just been locking the doors from the inside by hand and then using the key after to arm the alarm. The sunroof has also stopped working, when I press the button you hear a noise but nothing else happens. The battery was changed a while ago. I was thinking about changing the navi so that I can have it on at all times but I'm not sure which one to switch to since everything else (A/C/radio/tape) runs through that screen on the car. Any help would be appreciated.

Edit: The house light isn't working either. It doesn't matter if I put it on door or on, doesn't turn on. But I can click the button and it will turn on.

Thank you.

 

Any advice folks?
