Reviving old thread in case anyone was wondering (like I did) if VLine is still worth it. Just installed in my 2006 Lx 470. First impressions are that it is. To address prior issues raised in this thread, I have an iphone so i don't know if the Android issues raised above are fixed or not.
Purchased in October, installed this weekend. Firmware shipped with it was the most recent so I didn't need to update.
Install was pretty easy for a novice like me. Took about 2.5 hours over two evenings after the kids went to bed including downloading apps and getting my phone connected. I have a small bit of buttoning up to do still once I make sure everything is working correctly and that I want to keep the unit in the glove box.
Removing the center stack was simple. There are many videos online about it, including one from GROM. Hardest part of that was removing the wood trim without breaking the tabs. The PO placed adhesive foam around the edge, so I think some had previously been broken and the adhesive was contributing to the difficulty. Many of the tabs broke, so I'll need to apply some tape as well.
One semi-challenging part was fishing the connections to the glove box where i placed the Grom unit. You have to run it over the right-center vent and down into the glove box. Takes some patience, but you can get it once you find the channel. Was helpful for me to shine a flashlight up from the glovebox once it was taken apart to see where the light went above the vent and where I needed to run the wires.
The other issue I had was where to place the gps antenna. Other posters recommended placing near the passenger's side A-pillar, which is what I did, but I couldn't find anyone online explaining how to do that. Partially writing this so it might help someone in the future. Taking off the A-pillar is easy. Pry off the two screw covers from the A-pillar handle and unscrew. You can then pull the A-pillar up and toward you and it comes out easily. There is a small channel in the dashboard under the A-pillar that you can fish the antenna connection down to the glovebox. It is very easy. Again, the flashlight trick helped me here.
Had a small issue getting carplay and bluetooth to connect the first time. Had to delete the VLine from my phone's bluetooth memory, relearn, and it's worked well since. Music is high quality, so high that i didn't realize the cheap tape adapter I was using before must not have been broadcasting the subwoofer channel. Subwoofer rattles, so I need to put that on the list of things to replace now. Door speakers and tweeters seem in good enough shape that they're not a priority.
VLine wasn't cheap, but it was worth it for me. I travel a fair bit for work and the truck was purchased to be a road trip mobile, so having those directions easily visible driving is a must. Music sounds great and ease of connection (so far) would have sold me even if carplay wasn't included.
