just got my 2010 isport last night!
i have already been looking into this like crazy because a2dp is the most important thing for me and that feature was lacking on the base model
so i have narrowed it down to a couple options for my solution:
1. buy a new unit that supports everything (kinda) and is plug and play (kinda) like the unit from navitouch (dot) ca ~$600
2. add a regular deck that supports the options i want and then deal with not using the lcd up top or steering wheel controls unless i pony up the cash for the module that i have heard dosnt even work correctly. ~$400 and up
3. stick with everything stock and get something like the xcarlink (though im pretty sure this dosnt support controls via blue tooth..which would suck) ~$130
for now i think im going to go with the navitouch unit..all and all its not that much (all things concidered) and it gives me all kinds of functions as apposed to most functionality i desire. as with everything im sure its not perfect, but its probably close enough for my purposes...i hope..lol
