I know almost nothing about navigation systems, but my employer is willing to pay for one for my 2005 Dodge Ram 2500 CTD. It currently has the existing factory AM/FM/CD head unit.
I'd sure appreciate some help with these questions.
1. Which is better, the factory in-dash navigation system or an aftermarket? I want it to look clean and like it belongs.
2. Are there 2 kinds of factory systems? RB1 and RB4? Which is better?
3. I saw a Pioneer AVIC-Z1. Would that fit in my truck?
4. What is "double DIN"? I don't think I have that.
Any help would be welcome. Thanks for your time.
