what disc will upgrade my 2003 navigation ?

 

the 2003 upgrade disc will fix you up- they are all year and model specific and color coded
Check on www.acura.com
stores area and -purchase nav dvd
need your VIN number to get right one
also register while you are there- as car owner

is that the only choice?

 

yep- they actually ship direct from Alpine stereo company and thats the only disc that will work in your unit, cant use an mdx disc or anything like that
No you cant copy someones disc- (you can with right equipment but its illegal)
they are $200, maybe less now, and you upgrade every 3-4 years, most used TLs never got a new disc- the owner didnt know you could

 

if some did know its $200. they passed. thats a bit high !!!!!!!!!

 

I got a card/advertisement from Acura that offered the updated Nav DVD for $150; so don't pay too much!

 

you need version 2.50 on acuranavi.com
