Damn do I hate Pioneer for what they did to this unit....
Yet, this is the ONLY device on the market today that is capable of modding the interface. My Nav unit right now with all my mods is UNTOUCHED in features and in graphics to anything that is on the market today, and believe me I have looked because if there is a unit that looks and fuctions better than what I have done with it, I will buy it in a heartbeat. Trust me though, I have looked!
I been wanting to just build my own unit but with the same dimensions as the AVIC, so far though I have other things to take care of in the time being but since iGo 8.3 exists in different variants I know this kind of project can be done.
I was looking at the following: http://www.mini-itx.com/store/?c=39
I don't exactly know how big the dimensions are for the mini-itx but the smaller the main board the better, in terms of space but if a mini-itx board can fit in that same space as an avic then I can see better results to what can be installed.
The project was simply installing a Windows 7 base OS but this in general is because I want to the Zune support for it. But there are projects that exist such as http://wiki.openice.org/index.php?title=Main_Page which are linux variants that can run on lighter systems with lesser load. Either way I am done buying name brand nav systems, I am just going to design my own. For the nav system though I was thinking of just installing a EDGE/HSPA card where all I do is install a SIM from a GSM carrier and use that as the car phone with it's own number or make it easy to simply swap the SIM and be done with it and the need for bluetooth is gone for me at least. With a data card and the capabilities of a computer since it will have access to the internet running a java based version of Google Maps such as in a cellphone or Bing Maps I can have free GPS Navigation that updates on the fly as I drive.
Of course coverage of your carrier will defenitely effect that coverage and same with speed of the network, but I still wanted to try the idea because that way I don't need to pay for map updates every year at all. The rest is simply adding functionality. Installing a high quality video card on to these tiny boards with sub out can also bring out that high quality audio that is expected from such units as well.
I am just posting this up in hopes that by the time I come back from Afghanistan that someone has already started up on something like that, either way I am just doing some wishful thinking.
