All external attenas created equal?

They appear to be £30 or £10? Are they the same thing. Will they work with the 720T?

Thanks, Scott.

They will be close in terms of performance unless the cheap one really is a compromised design, why do you need one though? the GPS reception from the device as standard is great, even under demanding conditions - Mike

I am well aware as to what the external aerials are for, the point is you should only need one if you find the reception is poor due to the reasons you quoted, I have put my 720 under athermic glass and it works very well, it also works well in heavily built up cities. The GPS receiver in the newer devices is far better in terms of sensitivity IMHO than the earlier products, so if you used to use an external aerial you might find with the x20 you don't need it - Check first before you buy something you might not need - Mike

Thanks for the help guys.

The reason I was looking at them was my sat nav will be in a hole in the dash where the system fitted one usually goes. It will work but it will be buried under quite a bit of plastic.

If I have problems I will get a cheap one and stick it inside in a corner of the windscreen.
