My vehicle has the stock Navigation with DSP. Last year before my Thanksgiving drive from Dallas to Fort Myers I purchased the GROM bluetooth audio integration kit and its just one of the best implementations that I have seen to date. I bluetooth stream my music from my Pandora, I make phone calls from the steering wheel. For all that I need to do this system delivers. I know you do not have the OE system but if you did GROM would be a great way to go. Now If I were you I would just hold on because over these nest two years the electronics manufactures will have options that may very well just make sense for you to upgrade.
