cali TL

what up folks i jsut joined a few days ago after pickin up a 2000 white TL. This car is amazing but i guess i cant push it around too much becauce a new 5speed automatic tranny isnt in my budget. I saw that some people posted about how great the new NAV disc is so i went in today to get it, and they told me acura has cancelled shipment on all of the discs because there is a major bug in the software. Has anyone with the new disc had any problems with it? oh ya and i bought the 100,000 mile warrenty with acura, but i want to start moddin my whip, does anyone know what mods are allowed under warrenty?
