I have a 7" GPS I bought from ebay back in 2007. It uses WinCE 4.2 (could be 5.0, but i'm pretty sure it's 4.2). It's screen resolution is 480x234. I managed to get igo 8.0 working back then with sensis maps R14. Meanwhile, 4 years on in 2011, I am trying to update my system.
I am trying to update the software and have downloaded igo 8.3 but it doesn't work on my unit. I have downloaded the latest maps and have tried to overwrite the R14 maps on the old 8.0 software, but i don't think the R18 maps are compatible with 8.0 version.
I am worried that I am stuck with a working 7" GPS which I can't update the software or the maps. If anyone could help me, it would be greatly appreciated.
You will need a later version of igo8 for the late maps to work.

Where in the world are you?
If your unit has an sd card it makes it easier.
Dont forget to back up all the old files first in case you have issues.
