Well I think I have narrowed down the problem with my trip computer.

It works OK so long as I don't turn the air conditioner on!

When I do it goes on the blink.

I should say blank.

The display goes blank. Then a few minutes later it comes back, with strange times, such as 73.45 - not sure if that's am or pm. Much later it resets itself to a time and date it feels it needs to share with me.

So what does this mean. Do I have a problem with an earth or something?

Has anyone else solved this mystery?

you can buy a clock to replace it.
i have one, it was remanufactured years ago and it's still in it's box.

hahaha geez..its only trying to be friendly and tell u stories....at this exact time and date we was driving to somewhere....
