In my opinion... no.
Firstly: you've got to buy all of the stuff you need and that's not cheap.. ebay sellers are notorious for over pricing these things and I've seen them sat on ebay for months without selling You need the satnav unit, dvd drive, gps module and the top dash section with the clock and mini lcd display and all of the wiring plugs Trying to get all of that at current prices is going to set you back £400-500 for a 13yr old car... then factor in the cost of the map discs... which is unlikely to come with the unit and if it does will most likely be years out of date... A new one will add a further £140-150 to the cost.
Secondly: It won't give you bluetooth control even if you get a complete setup from a facelift accord and the additional BT module... you'll still be missing the steering wheel phone/voice controls.
When it comes to upgrades/mods you have to factor in the cost of the upgrade/mod vs the value of the car and any return you'll get on it... it's going to cost you anything up to 40-50% of the value of the car to buy/install (unless you get lucky and can pick up everything you need cheap) and it's not going to add any value to it. The car is already 13yrs old and realistically.. how much life does it have left in it.
I've been through the same thing... I wanted to upgrade my V2 satnav to the later V3 but It wouldn't get me BT or voice control and the only thing it would give me is the more up to date maps... From a value for money point of view... just not worth it on a car that I estimate will last another couple of years.
The cheaper option would be to get a USB system that plugs into the AUX socket on the rear of the unit, some of these will not only give you the ability to use you satnav on your phone, but BT as well... the most common ones would be xcarlink (iPhone only I believe) or the Grom kit... My only advice there is to do your research and never purchase anything from a company going by the name of carputershop or their business name of Mannocks.. they're grom resellers and are nothing more than cowboys who will try to rip you off, they lie, cheat and attempt to steal from customers. They are not part of grom (who I found to be exceedingly helpful with the problems I had with my Grom kit), so buy direct from them... Don't be put off by my bad experience with the kit... it had a faulty component somewhere and Mannocks refused to help troubleshoot it and tried to charge me up to £100+ to find out which part was faulty... Grom tried their best and even sent me some new leads from the USA for free whilst Mannocks wanted paying for replacements... and refused to refund me under my consumer rights for faulty goods. I had to take action to recover my money.. which I got back... But the whole experience with Mannocks was an unpleasant one that cost me about £50 to end up with the car as it was before I bought it.
There are loads of systems on ebay/amazon that will give you sound/music over the car speakers but no BT and can be found for less than £50, the grom kit will cost you £150 or so with BT and I have no idea of the xcarlink cost because I don't own an iPhone.
In my opinion... that's the way to go simply for the cost factor, and you can use your phones navigation which is free and more up to date.
I added a little magnetic mount for my phone so that it sits on the dash
