: Navigation Problems

03-08-09, 01:56 PM
I had to R&R my Nav system last week, and ever since then, it doesn't work. The GPS clock doesn't work, and the GPS itself, never finds my location. It has that little logo in the upper left corner that says there is no connection to satillite. I have pulled it at least 10 times since to try to see what happened. I have checked the antena, so I know it is pluged right. Everything else is good. Any ideas??? This is one of Jasons,CadillacSTS2003,conversions I bought last March. I have left him several messages, but no answer.

Definitely your GPS antenna is the problem. What was your R&R consisting of? Make sure the antenna is connected to the NAV unit. Also where is your antenna located, by any chance under something made of metal? So make sure the antenna has a “clear” view to the sky (i.e. not under some metal plate), is not near your cell phone and you don’t have tinted windows (certain tinted windows techniques are shielding the signal). Also you are not trying the system inside a garage or between some big tall buildings don’t you?
If nothings works get a new GPS antenna you can score one from Ebay for like $30 (Alpine). Here is what you should look for:

the email you sent to was probably cut off as i deleted alot of my old accounts after my recent separation

the problem is def the antenna, try relocating it somewhere else, do the vss calibration and see if its fixed

so true!

The antena is under the front dash cover, which is where it has allways been, and it worked perfect the week before. But I would like a longer wire, because to remove the radio, you have to remove the dash cover because of the short wire. So as long as the plug looks like that one from Alpine, I should be good??

Thanks Bill

kenwood nav antenna i have found works perfect
not 100% on alpine
as to why randomly it stopped working when unplugged, no idea, shouldnt be the case unless there was a short
i assume you d/c the battery when r&r the radio?

03-08-09, 08:49 PM
No I did not d/c the battery.:crying: Would this antena be right?

Hey Jason, is there a newer map version for this unit? I have V4.0.


03-08-09, 10:06 PM
version means nothing
enter the vin for any deville or seville with nav (like the vin i gave you to clear the vin out at the dealer)

the antenna LOOKS right however it doesnt say it will work on Kenwood navs, and it is a Kenwood nav antenna which i have already tried on other cars...

Went back and checked, and I don't remember you giving me a S/N. Mine was the new one and I didn't have to take it to the dealer. It worked when I pluged it in.

Recieved the new antena today. Installed it and it found my location in about 1 minute and workes perfect.

Thanks Guys!!!!!
