GPS / Inforad antenna

[NiceCupOfTea]

Hi, looking to get an antenna for my Inforad (my Garmin GPS V has never had any problems locating satellites) and saw this :

It talks about magnetic mounts, but in the picture I can only see a flat square - is there one of those little aerials that goes opposite it on the outside of the glass if you see what I mean? It's not pictured.

Or does that square thing just go on the bodywork interior somewhere?

the square bit is magnetic , just stick it where you want , do you have either a heated screen or metalised screen ? what car is it going in ?

Saab c900 - heated rear screen? could I use a sticky pritt pad?

[DennisTheMenace]

If the unit has an inbuilt ariel i cant see why its having problems seeing through your screen , you may have a faulty unit , how quickly does it pick up sats outside of the car ?

[NiceCupOfTea]

Don't know to be honest.... it sometimes takes half an hour to pick up sats

[DennisTheMenace]

send it back, it should pickup sats in a few mins if that after the inital start up

Bought it from Woolies - have managed to find receipt so guess I'll try changing it before I buy an aerial...

For the money I think the Inforad is brilliant. Through an unheated Focus windscreen it usually picks up a GPS position in a few minutes after switch-on. I was going to relegate mine when I bought a Navman but even after downloading the scamera data (not included) the Navman only gives a respectful chime when the offending box comes into sight. The Inforad nearly jumps off the dash if you are over the local limit. Has served me well to date. There are a few false positives around though and I don't like the PC software.
