general GPS advice required

[comwarrior]

I grabbed the Satnav from the car and it picks up it's location from inside the house.

i moved the unit to the garage and put the antenna on the garage roof. and still i get nothing but the start sequence...

Anyone got any suggestions?

My best guess is an incompatible antenna, somthing not made for the unit. What kind of antenna are you using, and where did you get it from? It can take a good hour or so when starting out completely from scratch (no backup battery) with the older units, with a little bad coverage. But it sounds like you have this covered.

I have purchassed a lot of stuff from ebay, and I have been pretty lucky with most of the things I buy. But once in a while, I get a dud. Hope that has not happened to you.

hi walter,
ok, i bought 2 gps receivers and two antenna's off ebay from the same seller.
The antenna's were separate sale from the receiver but it shows the antenna plugged into a receiver that looks like the one i got.


The antenna is a Rockwell Jupiter TU30 GPS module 's 27db GPS antenna and my receiver is a Rockwell GPS TU00-D200-401

Datasheet for the antenna is http://www.inpaq.com.tw/en/RF_Antenn...ed20100224.pdf

I hope that helps. Thanks

Hi,

Maybe you could wire it according to the manufacturer for RS232
and communicate with this:
