Looking for solution with Clarion Car Nav AV Unit - i.e. map upadate from US to NZ.

Need to find ways of reading the SD card; need also external active GPS antenna.

US map is displayed on the screen. SD card which comes with it is not readable in Lynux/Windows - anyone had experience with reading those SD Navi cards in car units?

I have no external GPS antenna to test reception on th ebench - looking for advice on making / reusing external active GPS antenna.

Clarion external GPS is powered by 5V (according to Service Manual)

As I do not have time to go to the wreckers to find external antenna - something like this:

I was looking at what I can reuse. Teared apart old Uniden in car box with foldable antenna - looks like that antenna is powered by 2.8V

Uniden GPS is working device - I'd rather give it away to somebody rather than take the antenna out of it (as if it will not work - I would not be soldeig it back again).

Anyone has experience with active GPS antennas? Voltage range, precautions for not burning device or antenna?

If you plan on using it as a full car stereo, before you go wasting a bunch of time, have you tested that it can pick up NZ FM stations? Lots of US stereos are locked down to only work on .1,.3,.5 where as NZ tends to use .2,.4,.6 steppings.

I would say you would be lucky to find NZ maps for a clarion unit, they are not super common over here.

I have put my fillers out and my auto mechanic mates are digging through the piles of junk in their garages to find me active GPS antenna, active FM antenna and rear car camera. So that it can be fully tested on the bench. As for the "time wasting" - I have invested thousands of hours of my time into Research and Development. It is all huge fun.
