There is like a bunch of different Alpine Navigation model number. Can someone tell me the difference between each model. i'm trying to decide which model to get. and the alpine webpage does not have any model besides this years.

NVE-N851A
NVE-N852A
NVA-N751A
NVA-N751AS

 

i wouldn't get the nva series navigation. those are cd based and one cd is only CA and NV, and IF you travel outside those areas, you would have to purchase another cd. I had the nve-n852a and loved it! it contained ALL of the US and parts of Canada. NOt that i needed it, but the DVD rom based nav is so much faster to upload and the user controls much easier. If you go off track, it automatically routes another way for you. Plus, the dvd nav is probably more updated.

the 851a is the old dvd based version... works just as good, but the 852 comes with a newer remote and updated streets and areas. I'd go for the 852a just because it's a newer version and quick and easy to use. This is coming from a guy who had all 3 in his car at one point in time...

 

Thanks Do Luck for the info. we still gotta all meet up and check out all our retrofits to compare man.
