cdnsupra:
I am planning same though hopefully sooner than April.
My desire is for 03 Accord voice Nav system but with portability.
I just printed reviews from "Pocket GPS" at:
http://www.pocketgps.co.uk/navman3400review.asp
Excellent reviews but must remember Europeans don't have Axim.
Another nice feature of this site is it gives you .wav files so you can compare voice nav voices.
Top packages now are Destinator 2 SmartST Pro US (best voice audio & 'todiefor' 3d view); Tom Tom package is highly rated for fast TTFF and I'm still researching.........
