Navigation system acts differently from phone call. It uses only driver side speakers to speak, while the passenger side speakers are still playing the radio or music.
no engine temp gage in dash ?

I think you've got that backwards. It'll flash when it's a little too hot and turn on steady if it's dangerously hot.

I like having the blue light. In winter my wife is notorious for turning the heat full blast the instant the cold engine is started. I try to explain that doing that acts like a radiator and will make it take LONGER for the engine to warm up and put out usable heat, but she simply won't believe me. Perhaps with the blue light I can now say "no heat until blue light goes off" and she'll get it.

(lol) You just found a usage for me on that blue coolant indicator as my wife often is doing the same thing ...I like having the blue light.

lol we used to argue about it on her old car... start the car, fan on Hi and temp on full hot immediately. I kept saying it will take LONGER if you do that when the needle is still on C! She was like "no it doesn't, it feels quicker to me". Yeah right. Meanwhile cold air was blowing on us.
The light goes out at 130f. I suspect that the engineers who designed the car thought it was a good idea.
I be leave that for the heat is on automatic the fan will not come on until the coolest warms up.

Didn't know that as we never use "Auto" mode on Automatic Climate Control System.

I highly doubt coolant temp hits 130*F that fast unless it is counting just what's in the engine before the thermostat opens.

This and a generic $10 sender (+ cheap gauge). You can put this adapter inline with any of the 5/8 heater hose on our car. Or you can get a T for the oem sensor and put a sender on it. Maybe for a water cooled turbo but even then..

My info is from a scan gauge I am sure it is engine coolent temp before the thermostat opens. I know I start to get heat at the same time.
hmmmmm.
I'm too lazy to go to the car and quote the page, however, if I remember correctly, it says in the manual that the blue light indicates the car rapidly heating up the catalytic converter in order to reduce harmful hydrocarbon emissions.
...but then again, it DOES happen to be a blue temperature gauge so...

We leave the setting at auto all the time. When it's cold out and the car is first started the fan runs very slowly. As the engine warms the fan increases in speed and after the blue temp light goes off you have heat.
And for ME! I'm guilty of doing that too! (eek)
