Heat Reflecting Windscreens

[Walt]

I am about to purchase a new Citroen Grand C4 Oicasso with a
heat-reflecting windscreen. Is this likely to affect my, yet
to be purchased, Sat Nav ?
If so, any suggestions please.

Thanks for any help

May not be the same at all, but my windscreen has fine wires for
heating... I thought it would totally bollix up the GPS reception, but
in fact doesn't affect it at all. I was surprised.

I'm not sure how the deposited film technologies would do however.
