receiver

I just bought a used 2013 CX-9. I added my iPhone to the receiver's Bluetooth list. On a different vehicle I have the receiver finds my phone within seconds. This Mazda takes several seconds. Is that normal? Anything I should be doing differently? Thanks!

I recently had water damage to the factory Sirius receiver in my 2007 CX-7, so I've been looking for a replacement box. The original was part number 0000-81-G01B, but it seems to be discontinued or unavailable everywhere I look. Is there a different receiver, different part number, that's...
