With my 05 Acura RL?

larrynimmo

i have an 07 acura that had an 05 NAV unit running 4.56a...it ran perfect. I changed my nav unit to an 06NAV and am now running 4.62.

I have not heard of any problems with 4.55 or 4.56 on any 05 vehicle.

I would also like to know. I just bought my 05 RL three weeks ago and am currently running version 4.13 in Dallas. It doesn't have several of the big roads and freeways that completed construction within the last 2-3 years. From what I've gathered, you can't install the 4.62 version successfully in the 05s, and if you do then you're lucky. Anyone with an 05 please post which discs you have successfully installed. I'm thinking of getting the 4.33 version.

4.55 should work fine in the 05 RL. I upgraded from 4.13 to 4.55 in my 05 prior to trading it in for an 06 and had no problems with it.

4.56a worked in mine.

I tried going from 4.13 to 4.63 on my 2005 RL and it did not work.

May be I need to go to 4.55 first.
Anyone know of any torrent etc. Did not find anywhere.
