kingdragonfly: I have purchased a new 7" Android car radio. It has an external GPS antenna.


However I was looking for an off-line option as a backup. I've read there's a number of free options, but I'm wondering if there's one with a good New Zealand map. Hopefully with a map that can be updated without spending a lot of money.

Also if anyone knows of software to test the GPS connection, perhaps identifying how many satellites and how good, I'd love to hear about it also.

Cheers
