One suggestion I have is to make sure that your phone is on the supported list. If your phone isn't compatabile you may run into issues. Other that that, I really like that headunit, SD would be very very nice feature to have.
Pretty funky looking headunit. Parrot makes quite a few bluetooth units that don't require a speacial headunit, they'll work with any headunit, designed for people with factory decks....and it work's great. Still plays through your system, sound out the speakers. For about $300 you get one of the higher end models with a phonebook. Alpine also has a similar one that will also play your iPod through...sound is much better than the fm transmitters.
What I like with this unit is taht no need of blutooth adapter all aready in. And that came with a micro like parrot to put on the sunvisor. And the best thing: I don't have to use the phone keypad to make call, the head unit can store 6 or 8 numbers plus the call display on the headunit.
I saw it at 148$ us with all the gear needed for the installation (wire harness, mounting kit and antenna adapter) but the ship only in US. I found it on an other site shipped for 122$ us without the gear.
Here at a distributor it is back ordrer....and elsewhere it is 160$ can + tax
