Can you go to the Settings->NavIQ Info Page and let us know the Device ID and Model Info that you are using?
It seems that the package that is being used does not correspond to the device resolution, hence you are seeing very small fonts and changing of the Map Font Size will not help in this case.
For the map updates, do register the Galactio software that you have at http://www.galactio.com/
and you can download the regular SLA map updates. For the SD card slot location, you might want to refer to the manual or contact the dealer that you have got it from.
I am more familiar with Garmin Nuvi GPS software, so I was stumped when my colleague asked me to help him out in his car GPS system. I have the following questions:
1. How do I make the font size bigger. There is one setting Map Font Size which I have already set to "Large" but it makes no difference whether I choose Small, Medium or Large. Font size remains the same. I am referring in particular to the text when I choose destination favourites or Map (see below screen). The text is so small that it is unreadable.
2. How do I update the map? Paiseh, but I cannot find the sd card slot, if any. Are the SLA maps downloadable free?
From what I can see, this is a Pioneer set (exact model I do not know) running Galactio V8.10.00.08. The map appears to be SLA EG v20131006 (TMC enabled).
