Has anyone determined if the 08 Scion Nav system by alpine is compatible with an 05? i have the 08 premium headunit in now but dont know if i need anything more than the external antenna?
(flame proof boxers because i'm sure this has been asked before)

 

Unless you can get a REALLY good deal on one, I'd just look for something aftermarket.

 

i second the aftermarket HU thought

 

well working on an ebay auction currently arround 400 for a "lightly used" model, hence why i asked if it will work?
