My new (old, lol!) 2005 Acura RL is a great car, but it’s missing a way to connect my phone to the car. The BT45ACU seems like the best option, even though it’s on the edge of stupid expensive. But I wanted plug and play install and no other mods required so I grabbed one from Crutchfield.

Install was about 2 hours with most of that being running the mic wire. Pulling out the trunk panels, the back seat and the door sills creates a pathway from the trunk to the dash, I stuck the mic low on the radio tower, next to my knee.

It took about 5 minutes to get the BT to link up, after that it’s been perfect. Hooks up within 5-10 seconds, cycles through phone functions quickly. iPhone 11 Pro-Max.

I’ll update this if anything changes, otherwise it’s a good product.

 

Does your nav screen properly display song metadata? What kind of phone are you using? I tried 2 different BT45 units from Crutchfield and neither would display metadata from my Pixels (4a 5G and 5a).

 

My nav screen displays song data if I activate the audio screen, otherwise it shows about ten characters of info on the top display. Good enough for me.

 

I bought a 06 rl a week ago now. Ive done a ton of looking for Bluetooth options, i love the bt45acu but everywhere is sold out. USA spec hasn't responded to my email I sent them.
Does anyone know where I can get my hands on a bt45acu?

 

I don't know that they make it new anymore, your best bet may be the resale market.

 

I'd consider selling mine. Bought off eBay about 6 months ago and never installed it.
